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?

Either LL or Ll
Either Ll or ll
Only LL
Only ll

Answer 1

Only ll

Explanation: Only ll is the answer to this test.

Answer 2

The likely genotype of a fruit fly with short wings is Only ll.

Step-by-step explanation:

There are two types of traits, Dominant and recessive. For a dominant trait only single copy of gene is sufficient for a phenotype to appear. So LL and Ll both will result in long wings. While in a recessive trait both copies should be identical for the phenotype to appear. only ll genotype will result in short wing fruit fly.
