Metaphase mitosis aligns chromosomes along the cell equator to prepare sister chromatids for separation into two diploid (2n) daughter cells.
Metaphase meiosis I aligns tetrads along the cell equator to prepare homologous pairs of chromosomes for segregation into two haploid daughter cells. The principle of independent assortment applies.
Metaphase meiosis II is just like metaphase mitosis, aligning chromosomes for sister chromatid separation, except it happens to the haploid number of chromosomes in each of the two daughter cells produced by meiosis I, producing a total of four haploid (n) gametes.
