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. In humans, the haploid cells made in meiosis are sperm and eggs. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a … WebOrganismal triploidy in humans is known to be lethal and causes early spontaneous abortions [].In contrast, aneuploidy is a well-tolerated characteristic hallmark of most human tumors [3,4,5].Moreover, many established tumor cell lines used as models for cancer research or pharmacological studies exhibit near-triploidy [] and many chemotherapy …
