Question

A plant of F1 generation has genotype "AABbCC". On selfing of this plant, the phenotypic ratio in F 2 generation will be (A) 3: 1 (B) 1: 1 (C) 9: 3: 3: 1 (D) 27: 9: 9: 9: 3: 3: 3: 1

Since AABbCC contains only one heterozygous allelic pair Bb, the cross would behave as monohybrid cross-leading to 3: 1 phenotypic ratio in F2 .Phenotypic ratio is 3: 1

Q. A plant of $F_{1}$ generation has genotype "AABbCC". On selfing of this plant, the phenotypic ratio in $F_{2}$ generation will be

3 : 1

1 : 1

9 : 3 : 3 : 1

27 : 9 : 9 : 9 : 3 : 3 : 3 : 1

Since AABbCC contains only one heterozygous allelic pair Bb, the cross would behave as monohybrid cross-leading to 3 : 1 phenotypic ratio in $F_{2}$ .
Phenotypic ratio is 3 : 1
