Question

What is the phenotypic ratio of F2 generation in a dihybrid cross?

(a) 3:1

(b) 1:2:1

(c) 9:3:1

(d) 9:3:3:1

I got this question during an interview.

The above asked question is from Inheritance of Two Genes-2 in portion Principles of Inheritance and Variation of Biology – Class 12

Answer 1

Right answer is (d) 9:3:3:1

For explanation I would say: The F2 generation in a dihybrid cross produces all possible phenotypes. The ratio obtained for it is 9:3:3:1.
