When Does Separation Of Homologous Chromosomes Occur

WebThe homologous chromosomes are arranged at the metaphase plate of the cell in metaphase I. In anaphase I, the homologous chromosomes are separated. In prometaphase II, microtubules attach to the kinetochores of sister chromatids, and the sister chromatids are arranged at the metaphase plate of the cells in metaphase II. WebThere are two possible homologous chromosome arrangements at the equatorial plane in metaphase I, that are then separated during anaphase I. The total possible number of different gametes is 2n, where n equals the number of chromosomes in a set. In this example, there are four possible genetic combinations for the gametes. logic pro refills boxWebChromosomes line up with homologous pairs.
