Typical Ratios Resulting from Epistatic Interactions in Dihybrid Crosses Would

Question

Typical ratios resulting from epistatic interactions in dihybrid crosses would be ________.
A) 9:3:3:1, 1:2:1
B) 1:1:1:1, 1:4:6:4:1
C) 9:3:4, 9:7
D) 1:2:2:4:1:2:1:2:1, 1:2:1
E) 3:1, 1:1

Accepted Answer

Typical ratios resulting from epistatic interactions in dihybrid crosses would be 9:3:4, 9:7. These ratios are the result of interactions between two genes where one gene masks the expression of the other gene. In the case of 9:3:4 ratio, one gene is dominant over the other gene, while in the case of 9:7 ratio, one gene is dominant over the other gene but the recessive allele of the second gene can still express itself.
