BRAINCAKEIndependent Segregation of Chromosomes
During meiosis 1 the 23 homologous chromosomes line up on the equator side by side arranged in a random order.
Which chromosomes go to which daughter cell is a matter of chance.
This random alignment of chromosomes leading to different combinations of paternal and maternal chromosomes in the daughter cells is called independent segregation.
