Rollers – Sex Linkage
I struggled with this topic until I read Frank’s page on it. This article helped me understand how it works for those things that are sex-linked. This topic probably should have been at the start of the document, however once you grasp the concepts it probably won’t be read again. Sex-Linkage by Frank Mosca Sex!! […]
Rollers – Breeding Result Expectations
Our thanks again to Mr. Mosca for allowing us to use his material. All fanciers should study this page to gain an understanding of how the colors and patterns are passed along to the offspring. This section is two pages. Do not overlook the link at the bottom to go to the second page as […]
Rollers – Selfs
I have included this page just to clarify a point. “Self” refers to a bird being a solid color. Selfs are not a single genetic trait, rather it is a term for how a bird looks. There are several ways to get them.
Rollers – Almond
The following text is from Frank Mosca. Pictures above are from J.P. Isom. Step 1: Almond is a dominant, sex-linked, depigmenting mutation — or change from the wild-type condition of the pigeon, (Columba livia). Beside the depigmentation, it does other things, too, and has many alleles (alternatives), but let’s not worry about those for now. […]
Rollers – Kite
The Kite I think we should include the following on kites from Joe Quinn’s book “The Pigeon Breeder’s Notebook” to help us keep quality kites in the loft to help with keeping quality Torts and Almonds. Formally Kites are t-pattern which show bronzing in the inner webs of flight feathers. The area showing the most […]
Rollers – Tortoise Shell
“Usually a combination of grizzle, kite, one dose of recessive red (optional) on a blue bird makes torts also known as tri-colour.” Sorry I can’t give credit for the description above, but I failed to note what forum I copied it from. I’ve always admired the torts in rollers but never knew what it took […]
Rollers – Masking Factors
Masking Factors These masking factors all work independent of each other and there is no order of dominance, therefore you can end up with a bird having any or all of factors. This young Tort has all the following factors: Grizzle, Recessive Red, Bald Head and Pied. All clearly visible on the bird. From the […]
Rollers – Patterns
There are 4 patterns and they are listed in order from least dominant to most. Here is an example of each. These examples are given in blue color palette but the same applies to ash red. The barless roller still has the colored wings and tail feathers. This is the typical blue bar pigeon with […]
Rollers – The Colors
There are three basic colors. They are listed in order of most dominant to least. There are only 3 colors, but several factors can tweak what we see. Even though we call the wild type “blue” in fact it is an optical illusion and truly a blue bird, but that is just too hard to […]
Color Basics
Mark’s Notes on Roller Inheritance There is some really good information on pigeon genetics on the Web but it is much more than I needed. Focusing on Rollers I’ve extracted the information that I need to keep the colors and patterns going in my loft. When I gave Dwight Madsen my flock of young birds […]
