Meiosis

Two successive divisions producing four haploid gametes with genetic diversity.

Overview

Meiosis I separates homologous chromosomes after recombination (crossing over) during prophase I, reducing chromosome number by half. Meiosis II resembles mitosis, separating sister chromatids. Key unique features include synapsis, crossing over, and independent assortment.

Cellular Location

Gonads (ovaries, testes)

Clinical Significance

Basis of sexual reproduction and genetic diversity; errors cause aneuploidy (Down syndrome, Turner syndrome).
