Assertion : GM salmon was the first transgenic animal for performing vaccine safety tests
Reason : For the production of GM salmon, genetically modified ova were fused with normal sperms of the same species.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Answer

D

Explanation

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 procuced by fusion of normal ova (eggs) with genetically modified sperms. The zyotes with modified gene developed into embryos which gace 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 fish to grow larger more rapidly than the non-transgenic shown.
