Accepted Answer

>

> [!TLDR]
> Meiosis II separates sister chromatids (like mitosis) in the two haploid cells from meiosis I, giving four haploid cells overall.
>
> **a. Meiosis II:**
>
> Meiosis II follows meiosis I without an intervening round of DNA replication (there is only a brief interkinesis). It occurs in each of the two haploid cells produced by meiosis I and closely resembles a normal mitotic division:
>
> - **Prophase II:** Chromosomes (each still made of two sister chromatids) condense again; the nuclear envelope breaks down and a new spindle apparatus forms.
> - **Metaphase II:** The chromosomes align individually at the equatorial plate, with spindle fibres from opposite poles attached to the centromere of each chromosome.
> - **Anaphase II:** The centromere of each chromosome finally splits, and the two sister chromatids separate and move to opposite poles of the cell. …
