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.

WebMetaphase. During metaphase, spindle fibers attach to the centromere of each pair of sister chromatids (see Figure below).The sister chromatids line up at the equator, or center, of the cell. This is also known as the metaphase plate. The spindle fibers ensure that sister chromatids will separate and go to different daughter cells when the cell divides.
