2.Within the context of human evolutionary genetics, what is linkage disequilibrium?

a.

Statement 3. Linkage disequilibrium describes a situation in which some combinations of alleles or genetic markers occur more or less frequently in a population than would be expected from a random formation of haplotypes from alleles based on their frequencies.

b.

Statement 1, 2, and 3

c.

Statement 2. When linkage disequilibrium = 0, then the population is said to be in linkage equilibrium.
