WebWithin the spindle, the bivalents are aligned in a pentagonal array with the X chromosome in the center ( Albertson and Thomson, 1993 ). The first meiotic division, which segregates chromosome homologs, is completed in approximately 15 min with the ejection of the first polar body (with a 2 n ploidy) during anaphase I. WebIn metaphase I, each pair of bivalents (two chromosomes, four chromatids total) align on the metaphase plate. This is different from metaphase in mitosis, where all chromosomes align single file on the metaphase plate. The position of each chromosome in the bivalents is random - either parental homolog can appear on each side.

WebSimilar to species with monocentric chromosomes, bivalents align at the metaphase I plate perpendicular to the spindle axis (Fig. 2f). A bipolar microtubule attachment to the two holocentric sister kinetochores per homologous chromosome and a monopolar microtubule attachment to the associated homologous non-sister chromatids was found ... WebBivalents, each composed of two chromosomes (four chromatids) align at the metaphase plate. The orientation is random, with either parental homologue on a side.
