WebMeiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells. WebFour haploid daughter cells are produced at the end, unlike two diploid daughter cells in mitosis. Meiosis 1 separates the pair of homologous chromosomes and reduces the diploid cell to haploid. It is divided into …
