Which of the following is involved in asexual reproduction?

A) sperm cells

B) egg cells

C) a zygote

D) none of the above

Asexual reproduction is where offspring arises from a single organism. So, in no way, can a human reproduction system, which is sexual reproduction, be involved in asexual reproduction.

You're answer would be D, none of the above.

The answer is D but remember, asexual reproduction refers to replicating the genetic DNA. If a sperm and egg cell were to fuse to form a zygote, there would be DNA from the mother (egg cell) and father (sperm cell), creating varying combinations. However, asexual reproduction creates offspring that are copies of each other. This is why none of the factors listed above are involved with asexual reproduction.
