Sagot :
Answer: A. The majority of the offspring population has functioning wings.
Explanation:
Since the flies are heterozygous for wing shape, their genotype would be Vv.
Therefore, the cross would be :
Vv x Vv -----> VV Vv Vv vv
From the above cross the different phenotypes associated with the progenies of the given genotype are as follows :
VV ---> functioning wings
Vv -----> functioning wings
vv----> vestigial wings
Thus, we can see that 3 out 4 progenies will have functioning wings i.e 75%
and 25% will have vestigial wings.
Thus, option A is correct.
