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.

What is a Metaphase Plate? What Happens in Metaphase of Mitosis
WebDuring metaphase I, a spindle apparatus forms and the paired chromosomes align along the equatorial pole of the cell. During anaphase I, the individual bivalents completely … WebMetaphase I. In metaphase I, each pair of bivalents (two chromosomes, four chromatids total) align on the metaphase plate. This is different from metaphase in mitosis, where … WebDuring metaphase I, homologous pairs move together along the metaphase plate, as kinetochore microtubules from both centrosomes attach to their respective kinetochores, the paired homologous chromosomes align along an equatorial plane that bisects the spindle, due to continuous counterbalancing forces exerted on the bivalents by the microtubules … fixhdcc
