Web11 nov. 2024 · What takes place in metaphase 1. In metaphase 1, the pairs of so-called bivalent chromosomes are completely condensed. Furthermore, there is no centrom division in metaphase 1 of meiosis while it does occur in metaphase of mitosis. They coincide with the metaphase plate between the poles. WebIn metaphase 1, each pole receives half the number of chromosomes, while in metaphase 2 it has the same number of chromosomes, but with only one chromatid. In metaphase 1, the chromosomes are released by the fibers of the spindle. In metaphase 2, after separation, each chromatid becomes a chromosome. WebIn 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 … knot for a lasso
