Because TYRP1 is part of the melanin assembly line, changes to this protein affect the proportions of melanins that are made. Grizzle is not sex-linked so the colors shade as the rest of the bird. reduced, almond, faded, Quinn-mutant, along with the three "basic" colors

All pigeons that you've ever seen, whether show or fancy pigeons like the Lahore, King, or Brunner Cropper, or whether flying birds like the Birmingham Roller, Racing Homer or Tippler, have been colored by one of these three pigments. The spread allele causes color to be evenly distributed across the body. the ash parent, you can also be sure it is not barless because barless is
In other animals, melanins also color hair, fur, skin, scales, and more. Instead, the raw materials are used mainly for making brown melanin, though these birds also make some red melanin. Back to top
