An individual who is heterozygous for two linked genes has the genotype A B/a b, which means that the A and B alleles are in one chromosome and the a and b alleles are in the homologous chromosome. Among the products of meiosis listed below, which are the recombinant types?

Question

Quizplus · Accepted Answer

Since the genes are linked, they are most likely to be inherited together. Therefore, the two parental types (A B and a b) are more likely to be produced during meiosis, while the two recombinant types (A b and a B) are less likely to be produced. In this case, the recombinant types are A b and a B, which have a non-parental combination of alleles. A B and a b are the parental types.
