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?

A. Either LL or Ll
B. Either Ll or ll
C. Only LL
D. Only ll

Respuesta :

It is D. Only ll
because if there was L in it at all it should have long wings.

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

What is the genotype of fruit flies?

In fruit flies, the dominant V allele produces lengthy wings, while the recessive v allele produces vestigial wings. Thus, flies with the genotype VV or Vv can have lengthy wings, and flies with the genotype vv can have vestigial wings.

There are varieties of traits, Dominant and recessive. For a dominant trait simplest single replica of gene is enough for a phenotype to appear. So LL and LI each will bring about lengthy wings. While in a recessive trait each copies have to be same for the phenotype to appear. simplest Il genotype will bring about brief wing fruit fly.
