Question

A cell resulting from fertilization of an egg begins to divide. Two cells are formed that normally remain attached and

Answer 1

Each cell that are divided will have complete genetic information itself. So both of them will survive.

Option A.

Explanation:

The sperm and the ovum fuse to form a zygote. This zygote then undergoes cleavage divisions to divide into many cells called morula. Now in the two celled stage, if the cells divide away from each other, it gives rise to monozygotic twins or identical twins.

Both the cell contains nucleus and chromosomes or DNA inside the nucleus. So both of them contains genetic information. Thus both of them survives and develops into two identical twins. This may develop into same amniotic sac or different amniotic sac.
