If AAbb \[\times \] aaBB, then phenotypic ratio of its progeny will be
A) 9 : 3 : 3 : 1
B) 1 : 2 : 1
C) 1 : 1 : 1 : 1
D) 4 : 1
Correct Answer:
A
Solution :
The phenotypic ratio will be 9 : 3 : 3 : 1. Dihybrid test cross gives 1:1:1:1 ratio Law of segregation gives 1 : 2 : 1 genotypic ratio in \[{{F}_{2}}\] generation.
