Question
In a dihybrid cross AABB × aabb, F2 progeny of AABB, AABb, AaBB and AaBb occurs in the ration of
Options
A.1 : 1 : 1 : 1
B.9 : 3 : 3 : 1
C.1 : 2 : 2 : 1
D.1 : 2 : 2 : 4
Solution
In a dihybrid cross the genotypic ratio can be represented as follows - assuming a cross between AABB and aabb :
So, the ratio of AABB, AABb, AaBB and AaBb will be 1 : 2 : 2 : 4.
So, the ratio of AABB, AABb, AaBB and AaBb will be 1 : 2 : 2 : 4.
