Which is the best description or sample of epistasis?
forsale [732]

Answer:

<em>a) Alleles at one locus can hide or mask the effect of alleles at another locus </em>

Explanation:

Gene interactions happen between genes at different levels and have implications in the phenotypic expression, causing a wide genetic variability.  

Epistasis means "interruption" and refers to interactions between genes located in different loci in the same chromosome. An “epistatic gene” can alter, influence, or suppress the expression of a "hypostatic gene". Epistatic genes might be either recessive or dominant. When the epistatic gene is recessive, the interaction is known as "recessive epistasis".  While when the epistatic gene is dominant, the interaction is known as "dominant epistasis"  

Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.
