Question

Identical twins result from a single fertilization to form a zygote, which then clones itself.

a) True
b) False

Answer 1

Identical twins do not result from cloning, but from the splitting of a single zygote.b) False

Step-by-step explanation:

False. Identical twins, also known as monozygotic twins, are formed when a single zygote divides into two separate embryos. This division can occur as early as the two-cell stage or during the blastocyst stage. When the division happens, each embryo develops separately and has its own placenta. Therefore, identical twins do not result from cloning, but rather from the splitting of a single zygote.
