What is epistasis? ? An interaction between a genotype and the environment that results in a continuous phenotypic distribution ? A situation in which the phenotypes associated with both alleles present in a heterozygote are observed ? A gene interaction in which the effects of an allele of one gene mask the effects of the alleles of a second gene ? A situation in which two different genes have redundant functions

A single phenotype that results from a combination of two different genes in which one gene interferes with the expression of another gene is known as (a) pleiotropy. (b) complete dominance. (c) incomplete dominance. (d) codominance. (e) epistasis.
When can epistasis be inferred? When the wild-type allele of one gene masks the expression of a mutant allele on another gene and expresses its own phenotype. When the mutant allele of one gene masks the expression of a mutant allele on another gene and expresses its own phenotype. When a haplo-sufficient gene produces a non-functional protein and expresses its own phenotype. When the mutant allele of one gene is masked by a wild-type gene and expresses its own phenotype.

Epistasis is a trait that can mask or affect the expression of a second gene.
