Question

You are studying the recently discovered Dusty gene in Drosophila Melanogaster where the mutant form makes the flies secrete a protein that looks like dust all over their bodies. The dust mutant is dominant in the wild type industry version. How you write the mutant form of the gene when notating it?

Answer 1

The Dusty gene will be written Dy

Step-by-step explanation:

In the particular case of Drosophila melanogaster, information about allelic relationships: dominance, recessivity or others is used at the same time, in combination with the relative frequency for the various alleles in the populations. An accepted designation for the two alleles of a genus is an uppercase italic letter to designate the dominant allele and the same lowercase italic letter for its recessive alternative form.

In this case as the mutant is dominant, Dy will be noted.
