What is the difference between meiosis I and meiosis II?

• In meiosis I, each pair of homologous chromosomes separates; each homologous chromosome from the pair is pulled toward an opposite end of the cell. In meiosis II, sister chromatids separate and four haploid daughter cells form.

• In meiosis II, each pair of homologous chromosomes separates; each homologous chromosome from the pair is pulled toward an opposite end of the cell. In meiosis I sister chromatids separate and four haploid daughter cells form.

• In metaphase II, each pair of homologous chromosomes separates; each homologous chromosome from the pair is pulled toward an opposite end of the cell. In meiosis I sister chromatids separate and four haploid daughter cells form.

• In metaphase I each pair of homologous chromosomes separates; each homologous chromosome from the pair is pulled toward an opposite end of the cell. In meiosis II sister chromatids separate and four haploid daughter cells form.
