Question

The phenotypic ratio of F2 generation in a monohybrid cross is:

• A. 1:2:1
• B. 3:1
• C. 9:3:3:1
• D. 2:1
  %Correct answer

Hint:

In a monohybrid cross, always remember the classic 3:1 phenotypic ratio, where the dominant allele appears three times more frequently than the recessive one.

Answer 1

The Correct Option is B

In a monohybrid cross, the typical phenotypic ratio in the F2 generation is 3:1, where three individuals exhibit the dominant trait, and one individual exhibits the recessive trait. This follows Mendel's laws of inheritance.
