Gene interaction, when recessive allele in homozygous state in one locus inhibits expression of dominant allele in other locus is:

a) Genetic heterogenity
b) Incomplete penetrance
c) epistasis
d) Locus heterogenity
e) Polygenic inheritance trait
f) C+E

I can't see any one them being an option. The only possibility I see is incomplete penetrance, which is when some individuals with a particular (dominant) mutation express a wild type phenotype.

Well in my opinion epistasis is the correct one, but according to answer sheet the correct answer is polygenic inheritance trait!

It cant be incomplete penetrance because then no phenotype is really hidden its just a intermediate of the parental phenothypes!

I can see how epistasis could fit as well; in fact, it fits a lot better than what I suggested. Still not sure how it can be polygenic inheritance though. Polygenic inheritance is when a single trait is controlled by 2 or more sets of alleles.
