Introduction:

The process of linkage and equilibrium of alleles are associated with the process of disequilibrium.

Answer to Problem 1P

Correct answer:

linkage disequilibrium: blocks of association between variants at different loci

Explanation of Solution

Disequilibrium in the linkage and association of alleles at two or more loci are related to each other. It is the difference between the observed frequencies of a combination of two or more alleles that are present on different loci.
