Question

Which is required for sexual reproduction?
mitosis
binary fission
diploid cell production
meiosis

Answer 1

We know that Mitosis is a process where a single cell divides into two identical daughter cells (cell division).
And we know that Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.

Answer 2

I would say that the answer is most likely meiosis.
