Web9 okt. 2001 · How Cells Divide. By Rick Groleau; Posted 10.09.01; NOVA; Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes. Web22 jan. 2024 · During meiosis, a diploid cell divides to produce four, non-identical haploid daughter cells, each containing a single set of chromosomes. In humans, these are sperm and egg cells. Unlike mitosis, meiosis involves two rounds of cell division. These happen across two stages: Meiosis I, and Meiosis II.
