Meiosis

Two coordinated divisions that reduce chromosome-set number and generate genetically varied haploid cells in sexual life cycles.

Overview

Meiosis uses programmed recombination, homolog pairing, cohesion, spindle attachment, and checkpoint control. Gamete formation and ploidy transitions differ across life cycles and taxa.
