Question

Quizplus · Accepted Answer

In the second generation of a cross of DDRR with ddrr, all the offspring will be heterozygous for both traits, resulting in the genotypes DdRr being the most common. This is due to the law of independent assortment, which states that during gamete formation, the alleles of different genes segregate independently of each other. Therefore, the likelihood of any particular combination of alleles is the product of their individual probabilities of occurrence.
