WebHumans have 23 chromosome pairs, which results in over eight million (2 23) possibilities. This number does not include the variability previously created in the sister chromatids by crossover. Given these two mechanisms, it is highly unlikely that any two haploid cells resulting from meiosis will have the same genetic composition ( Figure 7.4 ). WebSep 4, 2024 · Meiosis is a type of cell division in which the number of chromosomes is reduced by half. It occurs only in certain special cells of an organism. 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 …

WebAnswer (1 of 2): In the gonads i.e. the ovaries of the female of the species, and testes of the male. These are the organs in which gametogenesis (sex cell/gamete formation) occurs. … 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 ). fizzy fairy canada

WebO All sexual life cycles involve an alternation of diploid and haploid stages 0 Mitosis produces daughter cells with half the number of chromosomes as the parent cell. In animals, meiosis only occurs in the ovaries and testes O A normal human zygote has 46 chromosomes This problem has been solved! 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. 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. can not add an empty
