Crossing over in meiosis 1 random assortment

Crossing over in meiosis 1:
The crossing over in meiosis usually occurs when the homologous chromosomes transfer
information during the metaphase stage of meiosis 1. At this stage the homologous
chromosomes will line up on the metaphase plate as well as exchanging genetic
information. (varsitytutors.com Understanding Crossing Over - High School Biology Author

This diagram shows that each parent cell has pairs of the homologous chromosomes on
from their mother and one from their father moreover in meiosis the paternal and maternal
can be rearranged into daughter cells in multiple combinations. This will confirm genetic
variation in sexually reproducing organisms more genetic variation comes from the crossing
over which can take place during the prophase 1 of meiosis. (quora.com what are the

The principle behind independent assortment is that different genes and alleles that occur
are separately inherited at the time of meiosis of organisms which reproduce sexually.
Additionally, the independent assortment of the chromosomes is because of the fact that
independent division of chromosomes are turned into unattached gametes.
