WebThe reduction in chromosome number is achieved by the process of meiosis. In meiosis, there are usually two steps, Meiosis I and II. In Meiosis I homologous chromosomes segregate, while in Meiosis II sister chromatids segregate. Most multicellular organisms use meiosis to produce gametes, the cells that fuse to make offspring. WebAug 16, 2016 · Meiosis is divided in M I and M II. In the beginning of M I, one germ mother cell has 46 chromosomes, and at the end of M II, each of the generated four gametes will possess only 23 chromosomes. Before meiosis starts, the mother cell has the complete 2n set that is, 23 pair/46 chromosomes in its nucleus : Each chromosome is represented … WebMeiosis I.

This leads to a cell division that reduces the amount of DNA in each cell. … 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.
