There are many sites out there with a lot of scientific explanations of genetic inheritance, with a lot of confusing letters that look like “AabbCcDdpp”, for example. And there are sites with very simple explanations using squares and quadrants to show the ways that two genes each from two parents can combine to give you blue eyes or brown.
This site is intended to provide people who may not be scientists with a basic understanding of how color inheritance works and how we write about it scientifically, so that readers can then go on and understand the more scientific articles.
The discussion covers color inheritance and genetics in the Fancy Mouse. It doesn’t cover every possible combination, rather it provides an overview of the principles and “rules” involved. For other rodents, the principles generally remain the same, but the letters may be different and some colors may require more complicated combinations of genes and be harder to predict.
We hope you enjoy this discussion and that you learn a little something along the way.
Perms: The Different Coat Types
There are several different coat types you can have, too. There’s the plain old dominant short-haired coat, without any modifiers. There is a gene called Satin, which is recessive to normal hair, that gives a very shiny coat, usually written as “sa” for satin or “Sa” for not-satin.
Satin Coated Baby
A normal or satin coat can be straight or curly, using any one of several curly coated genes, “Re” for Rex, is dominant (surprise!) or “re” for not-rex. There is a “fuzzy” gene “fz” which is recessive, and a frizzy “fr” that is also recessive. A mouse can have all three or none.
BEW Angora Buck
Finally, the mouse can have long hair from the recessive angora “go” gene, or not. A mouse with both curly and long hair is known as “texel” and looks kind of like a tiny sheep, especially as a baby.

So, now you’re ready to take up your own research. Have fun!
