Definition of Meiosis II

Meiosis II refers to the second division in the process of meiosis, upon which sexual reproduction relies. As opposed to the first meiotic division that halved the number of chromosomes, in meiosis II what occurs is an equational division very much like a typical mitotic division. The sister chromatids of each chromosome are separated into two different cells. In this way, each of the four resulting haploid cells has a single set of chromosomes.

Stages of Meiosis II

  • The cells that enter meiosis II contain the haploid number of chromosomes.

  • But these chromosomes still have duplicated sister chromatids.

  • Therefore, the chromatids are reduced to one per chromosome during meiosis II

Prophase II

  • If the chromosomes decondense in telophase I, they condense again.

  • If nuclear envelopes are formed, they fragment into vesicles.

  • The centrosomes that were duplicated during interkinesis move away from each other toward opposite poles, and new spindles are formed.

Metaphase II

  • The sister chromatids are maximally condensed and aligned at the equator of the cell.

Anaphase II

  • The sister chromatids are pulled apart and move toward opposite poles.

  • Note that the chromatids of the chromosomes separate in this phase.

Telophase II and Cytokinesis

  • The chromosomes arrive at opposite poles and begin to decondense.

  • Nuclear envelopes form around the chromosomes.

  • Cytokinesis separates the two cells into four unique haploid cells.

Meiosis II and Human Health

Errors in meiosis II can lead to genetic disorders in which the number of chromosomes is incorrect. Most commonly this is aneuploidy, having more or fewer than 46 chromosomes. Chromosomal disorders can result in a range of developmental and health problems. For example, having an extra copy of chromosome 21 causes Down syndrome. Turner syndrome is a condition in which a female has only one X chromosome instead of two.

Research on the mechanisms of Meiosis II may greatly aid in the field of medicine. It helps scientists to understand mechanisms which form the grounds for genetic disease. Medical treatments, being capable of correcting chromosomal defects at the cell level, could therefore be applied to the curing or averting of genetic disorders.

Conclusion

Meiosis II is of central importance in sexually reproducing organisms to achieve genetic diversity and stability. It is possible by the separation of sister chromatids, as well as in the maintenance of the haploid state. This is a crucial genetic process that affects the very mechanisms of evolution and heredity.

Ongoing research continues to reveal more of the details of Meiosis II. It continues to promise new insights that can be capitalized with enormous potential, especially in genetic therapies and genetic disorders.

Frequently Asked Questions (FAQs)

1. What happens during Meiosis II?

Meiosis II separates sister chromatids into two cells, thus forming four haploid cells from an initial diploid cell.

2. ow does Meiosis II differ from Meiosis I?

Meiosis I separates homologous chromosomes, and decreases by half the number of chromosomes, and Meiosis II separates the sister chromatids but does not decrease further the number of chromosomes.

3. Why is Meiosis II important in genetics?

 Meiosis II ensures genetic diversity and correct distribution of the chromosomes. It truly is necessary for healthy sexual reproduction and, for evolutionary adaptation.

4. What are the stages of Meiosis II?

Stages of Meiosis II are:

  •  Prophase II

  • Metaphase II

  • Anaphase II

  • Telophase II followed by cytokinesis.

5. What errors can occur during Meiosis II?

Errors such as nondisjunction can occur, leading to genetic disorders like Down syndrome and Turner syndrome due to abnormal chromosome numbers.

6. Why is Meiosis II called an equational division?
Meiosis II is called an equational division because it results in daughter cells with the same number of chromosomes as the parent cell. Unlike Meiosis I, which reduces chromosome number, Meiosis II simply separates sister chromatids, maintaining the haploid state achieved in Meiosis I.
7. How does the duration of Meiosis II compare to Meiosis I?
Meiosis II is generally shorter in duration than Meiosis I. This is because Meiosis II doesn't involve complex processes like synapsis, crossing over, and homologous chromosome separation that occur in Meiosis I. Meiosis II more closely resembles a single round of Mitosis.
8. How does chromosome condensation in Prophase II compare to Prophase I?
Chromosome condensation in Prophase II is generally faster and less extensive than in Prophase I. This is because the chromosomes are already somewhat condensed from Meiosis I and don't need to undergo processes like synapsis and crossing over, which require a more relaxed state.
9. How does the concept of independent assortment apply to Meiosis II?
While independent assortment primarily occurs during Meiosis I, its effects are manifested in Meiosis II. The random orientation of chromosomes on the metaphase plate in Meiosis II further contributes to genetic diversity by determining which chromatids end up in which gametes.
10. What role does the nuclear envelope play throughout Meiosis II?
The nuclear envelope breaks down at the beginning of Prophase II and reforms during Telophase II. Its breakdown allows spindle fibers to access and interact with chromosomes, while its reformation at the end of the process creates distinct nuclei in each of the four resulting haploid cells.
11. What would happen if Meiosis II failed to occur after Meiosis I?
If Meiosis II failed to occur after Meiosis I, the result would be two diploid cells instead of four haploid cells. This would lead to the production of gametes with twice the normal number of chromosomes, potentially causing genetic abnormalities in offspring.
12. What would be the consequence of spindle fiber malfunction during Meiosis II?
If spindle fibers malfunction during Meiosis II, it could lead to improper segregation of sister chromatids. This might result in aneuploidy, where some gametes have too many or too few chromosomes, potentially leading to genetic disorders or non-viable offspring.
13. How does Meiosis II differ from Mitosis?
While both Meiosis II and Mitosis involve the separation of sister chromatids, Meiosis II occurs in cells that are already haploid (n) from Meiosis I, resulting in four haploid (n) cells. Mitosis, on the other hand, maintains the original ploidy level, producing two diploid (2n) cells from a diploid parent cell.
14. How does the spindle apparatus in Meiosis II compare to that in Mitosis?
The spindle apparatus in Meiosis II is similar to that in Mitosis. In both cases, it forms from centrioles (in animal cells) or microtubule organizing centers (in plant cells) and consists of microtubules that attach to the chromosomes' kinetochores to facilitate their movement.
15. What role do kinetochores play in Meiosis II?
Kinetochores are protein structures on the centromeres of chromosomes that serve as attachment points for spindle fibers. In Meiosis II, kinetochores enable the spindle fibers to pull sister chromatids apart during Anaphase II, ensuring proper chromosome segregation.
16. What is the main purpose of Meiosis II?
The main purpose of Meiosis II is to separate sister chromatids, resulting in four haploid daughter cells. This process ensures genetic diversity by creating gametes with unique combinations of genetic material.
17. How does cytokinesis in Meiosis II contribute to gamete formation?
Cytokinesis in Meiosis II completes the process of gamete formation by dividing the cytoplasm of the two cells resulting from Meiosis I. This creates four separate haploid cells, each with its own nucleus and cytoplasm, which will develop into mature gametes.
18. What is the significance of maintaining a haploid state throughout Meiosis II?
Maintaining a haploid state throughout Meiosis II is crucial for sexual reproduction. It ensures that when gametes fuse during fertilization, the resulting zygote will have the correct diploid number of chromosomes, preserving the species' characteristic chromosome number across generations.
19. How does crossing over in Meiosis I affect the genetic material in Meiosis II?
Crossing over in Meiosis I creates genetic diversity by exchanging segments between homologous chromosomes. In Meiosis II, these recombined chromosomes are separated into individual gametes, further increasing genetic variability in the resulting cells.
20. Why doesn't DNA replication occur between Meiosis I and Meiosis II?
DNA replication doesn't occur between Meiosis I and Meiosis II because the chromosomes are already duplicated from the S phase that occurred before Meiosis I. This ensures that the final gametes will have the correct haploid number of chromosomes.
21. What are the four stages of Meiosis II?
The four stages of Meiosis II are:
22. What happens during Prophase II?
During Prophase II, the nuclear envelope breaks down, the chromosomes condense, and the spindle apparatus begins to form. Unlike Prophase I, there is no pairing of homologous chromosomes or crossing over in Prophase II.
23. How do chromosomes align in Metaphase II?
In Metaphase II, the chromosomes align along the equatorial plane of the cell, similar to Mitosis. However, these chromosomes are already haploid, consisting of two sister chromatids each, as a result of Meiosis I.
24. What is the key event in Anaphase II?
The key event in Anaphase II is the separation of sister chromatids. The spindle fibers pull the sister chromatids apart, moving them to opposite poles of the cell. This results in each pole receiving a complete haploid set of chromosomes.
25. How does Telophase II differ from Telophase I?
In Telophase II, four haploid nuclei form, one in each of the four cell regions. This differs from Telophase I, where only two nuclei form. Additionally, the chromosomes in Telophase II are single chromatids, whereas in Telophase I, they are still composed of two chromatids.
26. Why is it important that centromeres don't divide during Anaphase II?
It's crucial that centromeres don't divide during Anaphase II because this allows the sister chromatids to be pulled apart as whole units. If centromeres divided prematurely, it could lead to chromosome fragmentation and loss of genetic material in the resulting gametes.
27. How does the behavior of chromosomes in Metaphase II ensure genetic diversity?
In Metaphase II, the orientation of each chromosome on the metaphase plate is random. This random alignment, combined with the crossing over that occurred in Meiosis I, ensures that each resulting gamete will have a unique combination of maternal and paternal genetic material.
28. How do cohesins contribute to chromosome behavior in Meiosis II?
Cohesins are proteins that hold sister chromatids together. In Meiosis II, cohesins remain at the centromeres until Anaphase II, when they are cleaved. This allows sister chromatids to stay together until the appropriate time for separation, ensuring proper chromosome segregation.
29. What would happen if cytokinesis failed to occur after Telophase II?
If cytokinesis failed after Telophase II, the result would be two binucleate cells, each containing two haploid nuclei, instead of four separate haploid cells. This would disrupt normal gamete formation and could lead to the production of abnormal reproductive cells.
30. How does the concept of genetic recombination relate to Meiosis II?
While genetic recombination (crossing over) occurs in Meiosis I, Meiosis II is crucial for distributing these recombined chromosomes into separate gametes. This process finalizes the genetic shuffling initiated in Meiosis I, contributing to the overall genetic diversity of offspring.
31. Why is it important that chromosomes in Meiosis II consist of two chromatids?
It's important that chromosomes in Meiosis II consist of two chromatids because this allows for the separation of genetic material into four unique haploid cells. Each chromatid will become a chromosome in one of the resulting gametes, ensuring proper genetic content in each.
32. How does the orientation of the spindle apparatus in Meiosis II affect the final arrangement of gametes?
The orientation of the spindle apparatus in Meiosis II determines the plane of cell division. In many organisms, this results in a linear arrangement of four haploid cells (like in spermatogenesis) or a tetrad arrangement (like in plant spore formation), influencing the final positioning of gametes.
33. What would be the consequence of premature sister chromatid separation in Meiosis II?
Premature sister chromatid separation in Meiosis II could lead to aneuploidy in the resulting gametes. Some gametes might receive extra chromatids while others would be missing chromatids, potentially leading to genetic disorders or non-viable offspring if these gametes participate in fertilization.
34. How does the behavior of centrosomes (or their equivalent in plants) differ in Meiosis II compared to Meiosis I?
In Meiosis II, centrosomes (or their plant equivalents) behave similarly to how they do in Mitosis. They separate and move to opposite poles of the cell to establish a bipolar spindle. This differs from Meiosis I, where they must accommodate the separation of homologous chromosomes rather than sister chromatids.
35. Why is it crucial that the chromosomes in Metaphase II are aligned precisely at the equator?
Precise alignment of chromosomes at the equator in Metaphase II is crucial for ensuring equal distribution of genetic material to daughter cells. This alignment allows spindle fibers from opposite poles to attach to sister chromatids, setting the stage for their accurate separation in Anaphase II.
36. How does the concept of genetic drift relate to the outcomes of Meiosis II?
While genetic drift itself is a population-level phenomenon, the random assortment of chromosomes in Meiosis II contributes to it. The chance arrangement of chromatids into gametes can lead to changes in allele frequencies in small populations over time, which is the essence of genetic drift.
37. What role do motor proteins play in chromosome movement during Meiosis II?
Motor proteins, such as dynein and kinesin, play a crucial role in chromosome movement during Meiosis II. They interact with microtubules of the spindle apparatus to generate the forces necessary to separate sister chromatids and move them towards the cell poles during Anaphase II.
38. How does the concept of genetic load relate to errors in Meiosis II?
Genetic load refers to the reduced fitness in a population due to the presence of deleterious alleles. Errors in Meiosis II, such as nondisjunction, can lead to aneuploidy and the expression of deleterious alleles, potentially increasing the genetic load in a population.
39. Why doesn't interkinesis (the brief interphase between Meiosis I and II) involve DNA replication?
Interkinesis doesn't involve DNA replication because the chromosomes are already duplicated from the S phase that occurred before Meiosis I. Replicating DNA again would result in gametes with twice the correct amount of genetic material, disrupting the proper halving of chromosome number in meiosis.
40. How does the behavior of chromosomes in Anaphase II ensure genetic uniqueness in gametes?
In Anaphase II, sister chromatids are separated and moved to opposite poles. This separation, combined with the random assortment of chromosomes in Metaphase II and the genetic recombination from Meiosis I, ensures that each resulting gamete has a unique genetic makeup.
41. What would be the consequence of a mutation affecting the attachment of kinetochores to spindle fibers in Meiosis II?
A mutation affecting kinetochore-spindle fiber attachment in Meiosis II could lead to improper chromosome segregation. This might result in aneuploidy, where some gametes receive too many or too few chromosomes, potentially causing genetic disorders or non-viability in resulting offspring.
42. How does the concept of genetic bottleneck relate to the outcomes of Meiosis II?
While a genetic bottleneck is a population-level event, the random assortment of chromosomes in Meiosis II can contribute to its effects. In small populations, the chance distribution of alleles into gametes during Meiosis II can lead to reduced genetic diversity, which is characteristic of a genetic bottleneck.
43. Why is it important that the spindle checkpoint is functional during Meiosis II?
The spindle checkpoint is crucial in Meiosis II to ensure that all chromosomes are properly attached to the spindle before Anaphase II begins. This prevents chromosome missegregation and the formation of aneuploid gametes, which could lead to genetic disorders or non-viable offspring.
44. How does the behavior of the cytoskeleton differ in Meiosis II compared to Meiosis I?
In Meiosis II, the cytoskeleton behaves similarly to how it does in Mitosis, forming a bipolar spindle to separate sister chromatids. This differs from Meiosis I, where the cytoskeleton must accommodate the separation of homologous chromosomes, often forming a more complex spindle structure.
45. What would be the consequence of incomplete nuclear envelope reformation in Telophase II?
Incomplete nuclear envelope reformation in Telophase II could lead to abnormal nuclear structure in the resulting gametes. This might affect gene expression and cellular function in the gametes, potentially impacting their viability or the development of the zygote after fertilization.
46. How does the concept of genetic hitchhiking relate to the outcomes of Meiosis II?
Genetic hitchhiking occurs when a neutral allele increases in frequency due to its proximity to a beneficial allele. While this is a population-level phenomenon, the separation of sister chromatids in Meiosis II can influence which alleles "hitchhike" together into gametes, affecting their frequencies in future generations.
47. Why is it important that sister chromatids remain attached at their centromeres until Anaphase II?
It's crucial that sister chromatids remain attached at their centromeres until Anaphase II to ensure proper chromosome alignment and segregation. This attachment allows both chromatids to be captured by spindle fibers from opposite poles, setting the stage for their accurate separation.
48. How does the energy consumption in Meiosis II compare to that in Meiosis I?
Meiosis II generally consumes less energy than Meiosis I. This is because Meiosis II doesn't involve energy-intensive processes like synapsis and crossing over. However, it still requires significant energy for processes such as spindle formation, chromosome movement, and cytokinesis.
49. What role do cohesion fatigue and maternal age play in chromosome segregation errors during Meiosis II?
Cohesion fatigue, the gradual loss of cohesion between sister chromatids, can increase with maternal age. In Meiosis II, this can lead to premature separation of sister chromatids, resulting in aneuploidy. This phenomenon partly explains the increased risk of chromosomal abnormalities in offspring of older mothers.
50. How does the concept of meiotic drive relate to chromosome behavior in Meiosis II?
Meiotic drive refers to the biased transmission of certain alleles or chromosomes to gametes. While often associated with Meiosis I, the behavior of chromosomes in Meiosis II can also be influenced by meiotic drive systems, affecting which chromatids are more likely to end up in functional gametes.
51. Why is it important that the mitotic spindle in Meiosis II is perpendicular to the plane of division from Meiosis I?
The perpendicular orientation of the mitotic spindle in Meiosis II relative

Directions for question:

Two friends Moloy and Niloy passed out from the Purulia Institute of Science and Technology with B.Tech degrees in Mechanical Engineering, but even after a year placement was hard to find. So they decided to take the challenge head-on, came down to Kolkata, rented a garage space on Park Street, and having an affinity towards making people enjoy good food, started their firm named 'B.Tech Bread-Omlette Wala'. 

They started with three items on the menu. One was the French Toast which could be prepared in 3 minutes. The second was the Egg Tortillas which took 15 minutes to prepare. Any one of Moloy and Niloy could prepare any one of them at a time. The third was the Egg Bhurji with French Fries. This however was prepared on an automated fryer which could prepare 3 servings at a time and took 5 minutes irrespective of the number of servings equal to or below 3. The fryer did not need anyone to attend to it, and the time to put in the raw ingredients could be neglected. So one could tend to the preparation of other items while the Egg Bhurji with French Fries were being prepared. 

They wanted to serve the orders as early as possible after the order was given. The individual items in any order were served as and when all the items were ready, and the order was then considered closed. None of the items on the menu were prepared in advance in anticipation of future orders. 

On the first day, 3 groups of customers came in and ordered at 6.00 pm, 6.10 pm, and 6.13 pm. The first order was for a plate of Egg Tortillas, two plates of French Toast, and three plates of Egg Bhurji with French Fries. The second order was for a plate of French Toast and two plates of Egg Bhurji with French Fries. The third order was for a plate of Egg Tortilla and a plate of Egg Bhurji with French Fries. 

On the backdrop of the above information answer the questions given :
