These cells are our sex cells – sperm in males, eggs in females. Meiosis in humans happens before birth in females, and constantly after puberty in males.

WebMeiosis begins with a diploid somatic cell which contains 46 chromosomes, or 23 pairs of homologous chromosomes. One pair of homologous chromosomes is composed of a maternally- and paternally-derived chromosome, each of which has the same genes at the same loci but differing alleles, which are different versions of the same gene.
