Solution

The correct option is D Both Assertion and Reason are incorrect
Genetically modified (GM) organisms are those organisms that have their genetic material modified to meet some desired conditions. They generally carry a foreign gene in their DNA. GM salmon was the first transgenic animal for food production. It was produced by fusion of normal ova (eggs) with genetically modified sperms. The zygotes with modified gene developed into embryos which gave rise to much bigger adults than either parent thus have greater food value. It is achieved by addition of a gene that codes for the growth hormone that allows the first fish to grow larger more rapidly than the non-transgenic salmon.
So, the correct answer is 'Both Assertion and Reason are incorrect'.
