Which of the following patterns of inheritance describes interactions between multiple genes?
A. Epistasis
B. Sex linkage
C. Codominance
D. Simple dominance
E. Homozygous recessive
Answer (2)
The answer is (A.) Epistasis.
The correct pattern of inheritance that describes interactions between multiple genes is epistasis. It occurs when the effect of one gene is masked or modified by another gene. An example is seen in Labrador retrievers, where one gene determines coat color and another gene can mask that color expression.
