Explain what is epistasis and how is it different from dominance?

Dominant epistasis happens when thedominant allele of one gene masks the expression of all alleles of another gene. If an organism inherits one or two copies of the dominant allele, they will have the trait. ... Heterozygous means that two different alleles for a trait are inherited instead of two of the same allele.

I hope this helps :)
