Bivalents align at metaphase plate what phase

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. WebMetaphase I: Bivalents, each composed of two chromosomes (four chromatids) align at the metaphase plate. The orientation is random, with either parental homologue on a side. This means that there is a 50-50 chance for the daughter cells to get either the mother's … Meiosis: Homologous chromosomes pair forming bivalents until anaphase I … This section is under development.
