C) physical linkage.
D) linkage equilibrium.

Question

Quizplus · Accepted Answer

The interaction of alleles at different loci in nonadditive ways is referred to as epistasis. Pleiotropy refers to the phenomenon in which a single gene influences multiple, seemingly unrelated traits. Physical linkage refers to the location of two or more genes on the same chromosome, while linkage equilibrium refers to the random association of alleles at different loci.
