In mammals, Meiosis occurs only in gamete producing cells within the gonads. During meiosis, homologous (paired) chromosomes separate, and haploid cells form that have only one chromosome … 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. incc materiais

WebMeiosis is a highly regulated cellular process for generating haploid gametes. During meiosis, programmed double-strand breaks (DSB) allow homologous chromosomes to synapse, crossover, and segregate accurately. Chromosomal errors during meiosis are known to result in infertility or congenital disabilities. Consequently, DNA damage … WebMeiosis in Animal & Plant Cells Meiosis is a form of nuclear division that results in the production of haploid cells from diploid cells It produces gametes in plants and animals that are used in sexual reproduction It has many similarities to mitosis however it has two divisions: meiosis I and meiosis II

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.
