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. church hiring websitesWebDuring metaphase, paired homologous chromosomes, which are still joined by chiasmata, align at the metaphase plate. These pairs, consisting of four chromatids, are called … church hiring sitesWebIn 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.
