Identify the phenotypic ratio of complementary gene action.
A. 9 : 7
B. 15 : 1
C. 13 : 3
D. 9 : 3 : 4
Answer: Option A
Solution (By Examveda Team)
The phenotypic ratio of complementary gene action is 9 : 7.Any hybrid cross of complementary genes gives a phenotypic ratio of 9 : 7.
A phenotypic ratio is a quantitative relation between phenotypes showing the number of times the frequency of one phenotype correlates with another.
Complementary gene action is when two different genes work together to contribute to one single trait.
