When homologous chromosome pairs align on the spindle during metaphase I the orientation of one pair is independent of the orientation of any other pair. This is known as independent assortment. Humans
have 46 chromosomes,
arranged as 23 pairs. During metaphase I each pair lines up independently, which
results in 24 possible combinations.
31. calculate the number of possible genetic combinations due to independent
assortment
