A)some genes were linked together

D)one of the pair of alleles is dominant to the other
E)some genes exhibit codominance

Question

Quizplus · Accepted Answer

Mendel's dihybrid crosses showed that gene pairs are sorted into gametes independently of other gene pairs. This means that the inheritance of one gene pair does not affect the inheritance of another gene pair, which is known as the Law of Independent Assortment. However, his monohybrid crosses only showed the segregation of one gene and its alleles, not the independent sorting of multiple gene pairs. Therefore, choice C is the correct answer.
