WebMeiosis occurs in the testes of men and ovaries of women. Meiosis and mitosis differ because: mitosis is a form of cell division which produces two identical, diploid body cells; 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.

WebMar 2, 2016 · Meiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells. WebAnaphase, anaphase I, and just like anaphase in mitosis, over here, the chromosomes start getting pulled apart, except for one significant difference, and this is actually a very …

Oogenesis occurs in the outermost … WebSpecifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired …

WebIn meiosis, the starting nucleus is always diploid and the daughter nuclei that result are haploid. To achieve this reduction in chromosome number, meiosis consists of one round of chromosome replication followed by two rounds of nuclear division. WebOct 27, 2024 · During prophase II of meiosis II, four important steps occur. These are the condensing of chromatin into chromosomes, disintegration of the nuclear envelope, migration of centrosomes to either pole, and the reconstruction of the spindle apparatus. However, centrosomes are not present in all cells. What Happens During Prophase II?

WebMar 24, 2011 · The two-stage process of meiosis begins with meiosis I, also known as reduction division since it reduces the diploid number of chromosomes in each daughter cell by half.
