who coined the term genetics and what are the characteristics of gene

Hello Saliha,

Genetics happens to be branch of biology dealing with the study of genes, genetic variation and heredity in organisms. A proponent of Mendel's findings and works, William Bateson coined the term genetics in 1905.

Coined by Wilhelm Johannes, a gene is the basic physical and functional unit of heredity. Genes are made up of DNA and every person has two copies of each gene, one inherited from each parent. Genes carry the information that determines one's traits, which are features or characteristics that are passed on or inherited from one's parents.

Some of the characteristics of genes are as follows:

1. Genes are functional units of heredity, variation, mutation and evolution and thereby determine the physical as well as the physiological characteristics of organisms.
2. Genes are situated in chromosomes and each gene occupies a fixed position named locus.
3. Genes express themselves by synthesis of proteins and enzymes, controlling cell metabolism.
4. By the process of replication, genes can produce a duplicate copy of themselves.
5. Genes may show a sudden change in expression from one form to another due to a change in composition called mutation.

Hope this helps you. We wish you the best for your future endeavours!

Regards

Hello,

Wilhelm Johannsen was the first person to coin the term genetics. He was a botanist.

Characteristics of Gene -

• It is present in cell of all living organisms
• They store hereditary informations about the organism
• They are located in Chromosomes and occupy a fixed position there.
• Genes show Mutation due to sudden change in its composition.

Hope this was helpful
