The Color coding of Pigeon

There are three genes responsible for pigmentation in pigeons.


  – Tyrp1 gene produces a protein that helps make the pigment eumelanin.
  Pigeons with blue-black feathers have normal Tyrp1. Ash-red and brown
  birds pigeons contain different mutations in the Tyrp1 gene, which
  leads to less or different pigmentation.
  
  – Mutations that affect the Sox10 gene override colors determined by
  various versions of the Tyrp1 gene. Regardless of whether the Tyrp1
  version makes pigeons blue-black, ash-red or brown, mutations that
  regulate the Sox10 gene result in red pigeons.
  
  – Mutation of the Slc45a2 gene decreases the intensity of colors
  determined by Tyrp1, Sox10 and their mutants. Depending on the version
  of the Tyrp1 gene – blue-black, ash-red, and brown − pigeons harboring
  the mutant Slc45a2 gene still display the same colors, but in
  watered-down or diluted versions, less intense than those with normal
  Slc45a2. For example, a pigeon with both the ash-red version of Tyrp1
  and the mutant Slc45a2 gene has ash-yellow feathers. Pigeons with
  Sox10 and Slc45a2 mutations are yellow, which is the dilute form of
  red.
