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 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. Meiosis occurs often because it allows body tissues in multi cellular organisms to repair themselves. Question 4.
