In reproductive cloning, a new organism is produced by fusing an enucleated ovum with:
AFlower-to-flower pollination
BRoutine yearly vaccination
CCellular waste excretion
DThe nucleus of a somatic cell
Answer & Solution
Correct answer: D. The nucleus of a somatic cell
1. Reproductive cloning avoids the need for a sperm.
2. It is done by fusing the nucleus of a somatic cell with an enucleated ovum.
3. A sperm is exactly what cloning avoids; red blood cells have no nucleus to donate and pollen grains belong to plant reproduction.
4. The sperm option traps students who assume normal fertilisation is involved.
