Consider two loci located close together on a single chromosome. These loci
A) carry alleles that will never segregate together.
B) are physically linked.
C) are in linkage equilibrium.
D) are likely to be broken up during recombination.

Question

Quizplus · Accepted Answer

Loci located close together on a single chromosome are physically linked. This means that they tend to be inherited together rather than independently, as they are less likely to be broken up during recombination. Therefore, option B is the correct choice. Option A is incorrect because alleles located close together on the same chromosome tend to be inherited together. Option C is incorrect because linkage equilibrium refers to the independent assortment of loci that are not physically linked. Option D is incorrect because loci that are physically linked are less likely to be broken up during recombination.
