Each step of meiosis
WebMitosis and meiosis are processes of cell division. In mitosis, a cell divides into two identical daughter cells. During this process, the original parent cell will replicate its genetic material, the chromosomes, and then each chromosome is split into two identical parts. The cell then divides into two daughter cells with the same genetic ... WebThus, the products of meiosis II are four haploid cells that contain a single copy of each chromosome. In mammals, the number of viable gametes obtained from meiosis differs …

WebTelophase I. o Chromosome #: 46. o Chromatid #: 92. End of meiosis I (in daughter cells) o Chromosome #: 23 ( That is why Meiosis I is called as reduction division, reduction in chromosome number to half) o Chromatid #: 46. Meiosis II [2nd Cell Division] is similar to Mitosis. Prophase II. o Chromosome #: 23.
