Chromosomes duplicate during metaphase
WebNov 20, 2024 · You might remember from above that it is the protein cohesin that holds together sister chromatids in metaphase of mitosis and metaphase II of meiosis. However, in meiosis I homologous chromosomes must be held together in metaphase I, before these ties are swiftly broken during anaphase I. WebDuring metaphase I, the homologous chromosomes are arranged at the metaphase plate —roughly in the midline of the cell, with the kinetochores facing opposite poles. Each homologous pair is oriented randomly at the equator. For example, if the two homologous members of chromosome 1 are labeled a and b, then the chromosomes could line up …
