Extracting a nucleus from a sheep cell and fusing it with the egg cell of a second sheep of the same species produces the first cell of a transgenic organism.
true or false.

If the nucleus of sheep Y’s egg is removed and we inject a nucleus from sheep X in the egg, it will function as X because the nucleus is the carrier of the genetic material that determine the functions performed by organism. However, if you mean a fusion between 2 nuclei of opposite sexes of the same species, it’s fertilization! It’ll yield a fertile offspring.
