Question

In fruit flies the allele for long wings (L) is dominant and the allele for short wings (l) is recessive. What is the likely genotype of a fruit fly with short wings?

Group of answer choices

Either Ll or ll

Only ll

Only LL

Either LL or Ll

Answer 1

A fruit fly with short wings must have the genotype that expresses the recessive trait. Since the allele for short wings (l) is recessive, the only way for a fruit fly to show the short wing phenotype is to have two copies of the recessive allele.

Thus, the likely genotype of a fruit fly with short wings is:

**Only ll**
