WebbMeiosis only occurs in the testes and ovaries, producing gametes (sperm and egg cells). This is known as reduction division. One diploid cell produces four haploid gametes, in two divisions. Human sex cells contain one chromosome from each of the 23 pairs. The four gametes produced in meiosis are genetically different.
