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 … WebTrisomy 13 (Patau syndrome). Trisomy 18 (Edward syndrome). Trisomy 21 ( Down syndrome ). In your genetic code, the 23rd pair of chromosomes are your sex cells that determine gender. Designations for sex cells are XX for female or XY for male, instead of as a number. When your cells divide, your sex cells can copy abnormally, causing a trisomy.
