Q. A plant of $F_{1}$- 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
Explanation
Since AABbCC contains only one heterozygous allelic pair, ‘Bb’, the cross would behave as monohybrid cross leading to phenotypic ratio in $F_{2}$-generation. [image:5c_image25.jpeg] Phenotypic ratio is 3 : 1
