WebCytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid. In humans, the products of meiosis are sperm or egg cells. [Does meiosis always produce four … WebThe answer is C. Meiosis I and Meiosis II. The centromere separates during anaphase, allowing the sister chromatids to divide. The 46 freshly released chromatids can be dragged to one end of the cell, while the other 46 can be dragged to the other end as the kinetochore spindle fibers shrink. 12.

WebOct 8, 2024 · Cells produced by meiosis in a diploid-dominant organism such as an animal will only participate in sexual reproduction. Figure 7.2. 4: Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct. Meiosis occurs in eukaryotic life cycles involving sexual reproduction, consisting of the constant cyclical process of meiosis and fertilization. This takes place alongside normal mitotic cell division. In multicellular organisms, there is an intermediary step between the diploid and haploid transition where the organism grows. At certain stages of the life cycle, germ cells produce gametes. Somatic …
