Although the process of meiosis is related to the more general cell division process of mitosis, it differs in two important respects:
Meiosis begins with a diploid cell, which contains two copies of each chromosome, termed homologs. First, the cell undergoes DNA replication, so each homolog now consists of two identical sister chromatids. Then each set of homologs pair with each other and exchange gene…Wikipedia · CC-BY-SA ライセンス について表示されるテキストウェブ2020年6月11日 · Learn about meiosis, the process of cell division that reduces the number of chromosomes in sexually-reproducing animals.
