Which of the following statements most accurately defines epistasis? Inactivation of the allele from one parent and expression of the the allele from the other parent. A single gene affecting a single trait. The inheritance of two or more genes close together on the same chromosome. The genotype of the mother determining the phenotype of the offspring. The alleles of one gene masking the dominant alleles of another gene.

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.

Complementary gene interactions occur when a pair of genes work together to create phenotypes for a single trait. This is caused by dominant alleles from one heterozygous locus masking other alleles, normally resulting in only two phenotypes: Incorrect term: Correct term: Question 3 Epistasis occurs when the alleles from one gene mask the genotype of another gene's alleles, resulting in fewer than the expected four phenotype classes. Incorrect term: Correct term: QUESTION Genetic redundancy is when a pair of genes can work together and often only require multiple dominant alleles from either locus to create a single phenotype. Incorrect term: Correct term:
