Solution

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’.
