WebWhen the genes are further apart on the chromosome, crossing over makes them less linked. Nondisjunction occurs when chromosomes fail to segregate during meiosis; when this happens, gametes with an abnormal number of chromosomes are produced. This can occur in Anaphase 1 and Anaphase 2 and can lead to gametes with too many or too few … WebTo put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes.

WebFertilization. Fertilization creates genetic diversity by allowing each parent to randomly contribute a unique set of genes to a zygote. While fertilization is not part of meiosis, it depends on meiosis creating haploid gametes. The fertilized cell restores the diploid number.

Prophase I is the first stage of meiosis I, followed by prophase II, anaphase I, anaphase II, metaphase I and metaphase II.

WebAnd you have your cytokinesis. So your cytokinesis, so these separate. These separate into two cells. So once again, when we did the overview of meiosis, we said look, the first phase of meisosis, you go from a diploid germ cell to two haploid cells. And these aren't quite our end product yet.
