Linkage disequilibrium refers to a condition in which
A)a set of SNPs recombine often.
B)a set of haplotypes recombine often.
C)a set of specific alleles of two or more genes tend to appear together.
D)a set of specific alleles of two or more genes only rarely appear together.
E)a haplotype block rearranges every generation.

Question

Quizplus · Accepted Answer

Linkage disequilibrium occurs when specific alleles of two or more genes tend to appear together at a higher frequency than would be expected by chance. This is often due to the physical proximity of these genes on a chromosome and can be used to identify regions of the genome that may be involved in certain inherited diseases or traits. Option A and B are incorrect as they refer to recombination rates, which are not directly related to linkage disequilibrium. Option D is also incorrect as it suggests that the specific alleles only rarely appear together, which is the opposite of what linkage disequilibrium implies. Option E is not accurate as haplotype blocks do not rearrange every generation.
