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 … WebThey are caused by nondisjunction, which occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis. The risk of nondisjunction increases with the age of the parents. Nondisjunction can occur during either meiosis I or II, with different results ( Figure 7.8 ).

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.

WebMeiosis takes place in two consecutive cell divisions, called meiosis I and meiosis II. The two cell divisions result in four daughter cells, rather than the two daughter cells in mitosis. Each daughter cell has only half as many chromosomes as the parent cell. The Stages of Meiosis: Interphase: Chromosomes duplicate before meiosis. WebSpores: specialized cells capable of forming a new organism; usually haploid and produced by meiosis. Reproduction by spores occurs in land plants and fungi. Parthenogenesis: …

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.
