WebbOccasionally during meiosis, chromosomes fail to separate normally into the four haploidcells, a phenomenon known as nondisjunction. In such abnormal meiotic divisions some of the haploid cells that are produced lack a chromosome, while others have more than one copy. The resulting gametes form abnormal embryos, most of which die. WebbMeiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote. What happens between these …
