Meiosis is the process of cell division that produces haploid gametes. In sexual reproduction haploid gametes combine through fertilization to form a genetically recombined diploid zygote. Meiosis includes two successive divisions and processes such as crossing over and independent assortment that increase genetic variability in gametes produced. Life cycles detail the events between meiosis and fertilization that vary for different multicellular organisms.
