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 … Web4 sep. 2024 · During metaphase I, the tetrads move to the metaphase plate with kinetochores facing opposite poles. The homologous pairs orient themselves randomly at the equator. This event is the second mechanism that introduces variation into the gametes or spores. In each cell that undergoes meiosis, the arrangement of the tetrads is different.

Web18 nov. 2024 · Meiosis. Meiosis describes the process of cell division by which gametes are made. In this process, we begin with a cell with double the normal amount of DNA, and end up with 4 non-identical haploid daughter gametes after two divisions. There are six stages within each of the divisions, namely prophase, prometaphase, metaphase, … WebMeiosis II is a mitotic division of each of the haploid cells produced in meiosis I.
