NEET Biology question
In dominant epistasis, a dominant gene(epistatic) masks the expression of another dominant or recessive gene (hypostatic) in a dihybrid cross; such an interaction gives a modified phenotypic ratio of
Answer: (B)
Solution
In dominant epistasis, the presence of a single dominant allele at the epistatic locus produces the same phenotype regardless of the genotype at the second (hypostatic) locus, so the standard dihybrid classes get rearranged into a modified ratio of
