The correct answer is: Organism will have extra nuclear genes of the recipient cell.
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.

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.
