Answer
b. gene pairs separate independently of other gene pairs
Work Step by Step
In genetics, independent assortment refers to the principle that during gamete formation, the segregation of alleles for one gene is independent of the segregation of alleles for another gene. This means that gene pairs separate independently of each other during the formation of gametes. This principle was elucidated by Mendel through his experiments with pea plants, where he observed that the inheritance of one trait did not influence the inheritance of another trait.
