Question

Phenotypic and genotypic ratio in $F_2$ generation in incomplete dominance is

• A. 1 : 2 : 1 and 1 : 2 : 1
• B. 3 : 1 and 1 : 2 : 1
• C. 9 : 6 and 3 : 1
• D. 9 : 3 : 3 : 1 and 1 : 2 : 1 : 4 : 1 : 1 : 2 : 1 : 2 : 1.

Answer 1

The correct option is A 1 : 2 : 1 and 1 : 2 : 1

Appearance of new phenotypes or intermediate phenotypes, other than parental phenotypes in progeny is incomplete dominance. In this, In the F2 generation, 1 red flowered plants(RR), two pink flowered plants(Rr), 1 white flowered plants(rr) are formed. So, the phenotypic and genotypic ratio is 1:2:1.

So, the correct option is ‘1:2:1 and 1:2:1’.
