Hi Arya,

Geneticist and Genetic Engineering both are Different Profession fields. I'll try to explain them in brief so that you can have clear picture of both.

Geneticist is Biologist or scientist, who studies the Science/History behind the genes, Its hereditary ( Passing of Genes from parents to Children) in many Living organism. Geneticist can hired for both agricultural and Medical Fields to perform general or complicated research on their respective genetic process. Patients who are having hereditary conditions, Mutation analysis, various disorders/diseases passed from their ancestors,  via genes are treated by Geneticist. Geneticist can opt for different areas of specialization such as

• Research and Development
• Gene Therapy
• Animal Breeding
• Biotechnology
• Forensic DNA
• Agriculture etc..

Genetic Engineering also known as Genetic Modification is  the process of alternation of the DNA of any living organism's genome by an artificial means and combining it with the DNA of other organism as a host. Genetic Engineering can be performed in various fields like Scientific Research, Agriculture and industrial Biotechnology. In Simple terms its Cross Breeding or modification Between DNA's of two Different organisms. Hope this information helps you to understand the difference between them.

Thanks & Good Luck!..
