Question

In a dihybrid cross, if you get 9:3:3:1 ratio it denotes that

• A. The alleles of two genes are interacting with each other
• B. It is a multigenic inheritance
• C. It is similar to monohybrid cross
• D. The alleles of two genes are segregating independently.

Answer 1

The correct option is D The alleles of two genes are segregating independently.

Cross involving two contrasting characters is called a dihybrid cross. The two flowers of each trait assort at random and independent of their traits and get randomly as well as independently rearranged in the offspring producing both parental and new combinations of traits.

So the correct option is "The alleles of two genes are segregating independently.".
