Use the information gathered in the Epistasis animation to answer the question. Although both dominance and epistasis involve masking of gene expression, they are different from each other. What is the major difference?

Dominance involves masking of one phenotype by another whereas epistasis involves masking of both phenotypes.
Dominance involves a gene that dominates whereas epistasis involves a gene that represses its own expression.
Dominance involves one allele masking another at the same locus whereas epistasis involves one locus masking a different locus.
Dominance is very common in gene expression whereas epistasis is a very rare phenomenon.
