What is ratio for recessive epistasis?

A. 12:3:1. Hint: In recessive epistasis the phenotypic expression of one allele is suppressed due to the allele of another gene, which is in homozygous recessive condition. … So, the ratio of recessive epistasis comes out to be 9:3:4.

What is the ratio of dominant epistasis?

Dominant epistasis- When the expression of both dominant and recessive alleles is masked by a dominant allele from another locus, it is called as dominant epistasis. Its ratio – 12:3:1.

What will be the phenotypic ratio of F2 generation if AaBb is crossed with AaBb?

9:3:3:1 is the phenotypic ratio of F2 -generation when the parents are having Aabb x aaBB alleles.
