Q:

Human gametes are produced by

A) Mitosis B) Meiosis
C) Replication D) None of the above
 
Answer & Explanation Answer: B) Meiosis

Explanation:

In humans all reproduction is sexual. It involves joining together haploid gamete cells from each parent with half the normal number of chromosomes to make a new cell containing both parents' genetic material. This is a diploid zygote. The cells from each parent that combine to form the zygote are called gametes.

 

Meiosis produces haploid gametes from a diploid parental cell.
