What is the definition of epistasis?(1 point) Responses when one trait is determined by multiple genes when one trait is determined by multiple genes when one gene affects multiple phenotypes when one gene affects multiple phenotypes when the allele of one gene interferes with the expression of another gene when the allele of one gene interferes with the expression of another gene when a dominant allele for a specific trait is not completely expressed over the recessive allele

Answer 1

Epistasis is defined as when the allele of one gene interferes with the expression of another gene. In other words, it is a genetic interaction where the effects of one gene are dependent on the presence of alleles at another gene.
