The genotypic ratio in the F2 generation in a monohybrid cross will be.
|
|
3:1
|
|
|
9:1
|
|
|
3:3
|
|
|
1:9
|
Explanation:
Detailed explanation-1: -Thus the genotypic ratio of a monohybrid cross is 1:2:1.
Detailed explanation-2: -The F2 progeny of a monohybrid cross showed phenotypic and genotypic ratios as 1 : 2 : 1 unlike that of Mendel’s monohybrid F2 ratio.
Detailed explanation-3: -F2 generation has genotypic and phenotypic ratio 1 : 2 : 1.
Detailed explanation-4: -So, the correct option is ‘1:2:1’.
