WebIn the male, meiosis takes place after puberty. Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. A single diploid cell yields four haploid sperm cells through meiosis. In females, meiosis begins during the fetal stage when a series of diploid cells enter meiosis I.

WebThe zygotic life cycle starts with syngamy and goes to meiosis. It has no diplont. Gametic life cycle goes from meiosis to syngamy. It has no haplont. Protists have all three types of life cycles whereas higher groups have only one. Animals exhibit gametic cycle, whereas plants\(_2\) retained the more primitive sporic cycle. WebProphase I of meiosis forms the tetrads. They line up at the midway between the two poles of the cell to form the metaphase plate. There is a chance of microtubule fiber to encounter maternally inherited chromosome. Orientation of each tetrad is independent of the orientation of other tetrads. 16.
