Verified step by step guidance1
Recall the principle of independent assortment, which states that alleles of different genes assort independently of one another during gamete formation.
Understand that this principle applies only when considering two or more gene pairs located on different chromosomes or far apart on the same chromosome.
Recognize that with only one gene pair, there is no assortment between different genes because there is only one gene involved.
Therefore, the minimum number of different gene pairs required to observe independent assortment is two.
Summarize that independent assortment involves at least two different gene pairs to demonstrate how alleles segregate independently.
