SpletMeiosis is described from males only (Fig. 2C, D). (No cells after pachytene were ob-servable, even in immature females, which generally provided numerous oogonial meta-phase plates.) Perhaps because of its small size, the Z-Z bivalent is undetectable as heteropycnosis during preleptotene and pro-phase I, even in Feulgen-stained prepara-tions. SpletMeiosis is how sex cells reproduce, dividing their chromosomes by half to create four haploid cells that are distinct from the original cells that birthed them. Meiosis has two different phases: meiosis one (meiosis I) and meiosis two (meiosis II). These phases are further divided into sub-phases, and metaphase one is a sub-phase of meiosis one ... SpletMeiosis ensures that daugther cells receive one of each type of gene and half the chromosome number. The mixing of genes independently provides a huge number of genetic combintations creating biodiversity.
