Hello. This question is incomplete. The full question is:
"In fruit flies long wings (W) are dominant to short wings (w).
what is the phenotype of the known parent?
a. wingless b. short winged c. medium winged d. long winged"
Answer:
It is not possible to respond through the information given.
Explanation:
In the question above, we learn that within a population of fruit flies, the "W" allele is the dominant allele and represents long wings, on the other hand, the "w" allele is the recessive allele and represents short wings.
Although this information is given, we cannot state the genotype of the known parent, if the genotype of an offspring has not been informed.
However, we can affirm that the parents that present the "ww" genotype will be considered short winged, while the parents that present the "Ww" and "WW" alleles will be long winged.
