WebTo achieve the reduction in chromosome number, meiosis consists of one round of chromosome duplication and two rounds of nuclear division. Because there are two rounds of division, the stages are designated with a “I” or “II.” Thus, meiosis I is the first round of meiotic division. Meiosis I reduces the number of chromosome sets from two to one. WebReview Questions 1. How many sets of human chromosomes are in each of the following cell types? * an oogonium * a primary spermatocyte * a spermatid * a cell from either sex during anaphase of meiosis I * a cell from either sex during anaphase of meiosis Il * a secondary oocyte * a polar body derived …

WebApr 26, 2024 · 1. In meiosis 1, it is said that chromosome numbers become halved in the two daughter cells. For example, in a 2n human cell there are 46 chromosomes. During meiosis 1, the cell will undergo interphase and probably the S-phase, where chromosome number becomes duplicated. Now the cell is 4n (i.e. 92 chromosomes).
