WebOct 27, 2024 · During metaphase, each chromosome is aligned and ready to be transported to either pole. As mentioned, a positive result to a spindle check must be completed before the move into anaphase, in which chromosome pairs are separated from their partners and transported to either side of the cell. What Happens During Anaphase I? WebMetaphase I. During metaphase I, the homologous chromosomes are arranged at the metaphase plate—roughly in the midline of the cell, with the kinetochores facing opposite …
