Re:

... over occuring in meiosis I in each of the cells and the fact that each of the cells is already different because of the independent segregation in anaphase I. If crossing over was exactly the same in every cell in meiosis I and there was no independent segregation, then we could draw a simple analogy ...

Genetics with Mitosis and Meiosis

Fellow bio-online members, please correct me if I got anything wrong. Anaphase (in any type of division) is after the genetic material has separated and is being pulled toward the ends of the cell. The cell cycle: G-1 S-phase G-2 M-phase (division) Mitosis: ...

Re: Mitosis and meiosis!

... there is crossing over occur. In Metaphase I, the homologous chromosomes are aligned at the equatorial line while metaphase in mitosis not. In Anaphase I, the homologous chromosomes are separated while sister chromatids are split at centromere in Anaphase of mitosis. You may get more info about ...
