Melanic Pigmentation of Domestic Fowl:
Autosomal Pheomelanin, Sex-linked Pheomelanin and Eumelanin
On this page you will find a listing of articles I have written for this blog dealing with pigmentation of the Red Junglefowl and its descendants, the Domestic Fowl. Each article is linked below along with a short description of the article. They are arranged in the order they should be read and are an addenda to my 2006 book, An Introduction to Color Forms of the Domestic Fowl.
A look at how the three types of melanin layer in the Red Junglefowl, or 'wildtype', color form that is commonly called "Black Breasted Red" in the hobby and that I refer to as Red Duckwing.
An overview of the basis of how this factor works in the domestic fowl.
In this part I look at how Autosomal Pheomelanin and its inhibitor interact with the five common e-alleles.
In this section I discuss the interactions of Autosomal Pheomelanin and its inhibitor with the common pheomelanic extenders, Columbian and Dark brown (called "ginger" in the hobby).
In this article I look at the genes involved in making various silver-based phenotypes ranging from dark golden through light golden to clean, non-brassy "white" silver phenotypes.
This article is complementary to #5 above, and is an explanation of how the many genetically different forms of "white" in the domestic fowl come about.
A paper I worked on establishing the agouti signaling factor in chickens.
