Sister chromatids separate during anaphase
|
Detailed explanation-1: -Meiosis II resembles mitosis, with one sister chromatid from each chromosome separating to produce two daughter cells. Because Meiosis II, like mitosis, results in the segregation of sister chromatids, Meiosis II is called an equational division.
Detailed explanation-2: -The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell.
Detailed explanation-3: -Meiosis II is the second division of meiosis. It occurs in both of the newly formed daughter cells simultaneously. Meiosis II is similar to Mitosis in that the sister chromatids are separated. It consists of 4 sub-phases: Prophase II, Metaphase II, Anaphase II, Telaphase II.
Detailed explanation-4: -Meiotic anaphase II is similar to the anaphase in mitosis. Both mitotic anaphase and meiotic anaphase II involves the separation of sister chromatids towards the opposite poles of the cell.
Detailed explanation-5: -Meiosis I is a type of cell division unique to germ cells, while meiosis II is similar to mitosis.
