Answer

In metaphase of meiosis homologous chromosomes line up on the equatorial ( metaphase) plate. At this time each chromosome is seen as two chromatids . The centromeres do not divide . At anaphase 1 when the kinetochore tubules to pull, each chromosome ( two chromatids) moves to one of the two poles of the cell without dividing--the sister chromatids remain together. In a phase of mitosis the centromere of every chromosome divides. The two chromatids of each chromosome separate so that only one chromatid of each pair of chromosomes moves to a pole.

Work Step by Step

The result of anaphase of meiosis 1 is that unidentical chromosomes move to opposite poles. In anaphase of mitosis the chromosome division and separation result in the same chromosome composition being pulled toward each pole
