There are two processes in meiosis that can cause variation:
- independent assortment
- crossing over
- occurs during metaphase 1
- homologous chromosomes move to the equator of the cell and line up.
- They arrange themselves on the equator and result in the formation of different gametes.
This creates 2 n new combinations of chromosomes in the next generation n =…
