Nucleus of a donor embryonal cell/ somatic cell is transferred to an enucleated egg cell. Then, after the formation of organism what will be true?
Organism will have extranuclear genes of the donor cell.
Organism will have extra nuclear genes of the recipient cell.
Organism will have extra nuclear genes of both donor and recipient cells.
Organism will have nuclear genes of the recipient cell.
Solution
The organism will have extranuclear genes of recipient cell. Since the recipient cell has already been enucleated (its nucleus is removed), the organism developing from it would have the nuclear genes of donor cell.
Related Theory
The egg cell is enucleated, so the organism will only have extranuclear genes from it. These genes are present in chloroplast and mitochondria and are transmitted along the cytoplasm. This results in cytoplasmic or maternal inheritance.
