Question

Meiosis does PMAT twice! That means there is a prophase I and a prophase 2. There is a metaphase1 and metaphase 2. Etc... How would you know whether it was in metaphase 1 or metaphase 2

Answer 1

Answer;

In metaphase I, the chromosome tetrads align on metaphase plate while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.

Explanation;

• Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes .
• Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
• During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.
