Dominant Epistasis and Recessive Epistasis

Dominant epistasis and recessive epistasis are both types of gene interactions that occur when alleles of one gene mask or modify the expression of alleles of another gene at a different locus. These interactions are important in understanding how genetic traits are inherited and expressed.

1. Dominant Epistasis: In dominant epistasis, the dominant allele of one gene masks the expression of alleles of another gene, regardless of whether they are dominant or recessive. This means that the presence of a specific dominant allele at one locus prevents the expression of alleles at another locus. Dominant epistasis is often represented by a 12:3:1 phenotypic ratio __________ ____ ___ ________ ________ ____ ___ ____.
