Metaphase refers to the (relatively) brief moment when chromosomes are aligned in the middle of a dividing cell. During , specialized cells divide to create gametes (sex cells). There are two divisions during meiosis so there are two metaphases.
During metaphase I, sister chromatids are still connected, forming the classic X-shaped double chromosome and they are aligned with their homologous partner (two Xs) that has the same genes.
After meiosis I, homologous chromosomes are no longer in the same cell so metaphase II is the single file arrangement of sister chromatids in the middle.
In short, Metaphase I is the separation of homologous chromosomes. Metaphase II is the separation of sister chromatids.
Here are two good animations that also help visualize the process. They may not be compatible on a mobile device.
