Question

$F_2$ generation of a dihybrid cross possesses one or both the dominant traits in proportion of

• A. 1/16
• B. 6/16
• C. 9/16
• D. 15/16

Answer 1

The correct option is D 15/16

In the Mendel dihybrid cross, in the F2 generation 16 progeny are formed. In this 9 are yellow round 3 yellow wrinkled, 3 green round and 1 green wrinkled. So in the 16 progeyn, 15 progeny show both dominant phenotypes or one phenotype. Only one progeny shows both recessive characters.

So, the correct option is ‘15/16’.
