On selfing a plant of $F_{1}$-generation with genotype " AABbCC ", the phenotypic ratio in $\mathrm{F}_{2}$-generation will be\

Professor PC Thomas Classes · Answer

(a) : Selfing is the process of fertilisation with polar or male gametes of the same individual. $\mathrm{A} A B b C C$ will produce two type of gametes $A B C$ and $A b C$. Thus, in $F_{2}$ generation three genotypes will be obtained. These are $\mathrm{AABBCC}, \mathrm{AABbCC}$ and $A A b b C C$ in the ratio of $1: 2: 1$. Phenotypically $A A B B C C$ and $A A B b C C$ are same. So, the phenotypic ratio in $F_{2}$ generation will be 3:1.\
