Jessica, The most extensive explanations I have seen are in the Malcolm B. Willis book: The German Shepherd Dog: A Genetic History. Dr. Willis is both a GSD breeder/judge and a geneticist. Sue Mazzeo From: Penny Kroh <Ketchy@xxxxxxxxxx> Subject: Re: colors in GSDs Date: Thu, 13 May 2010 05:29:38 -0400 Hey all! I am doing a project for biology (not due for a while but I'm very ambitious as I love genetics) and I thought, what better subject to pic than my favorite breed of dog? haha so, Does anyone have any good reliable sites on the color genetics of shepherds? I'm looking for info on which color genes are dominant and recessive, and info on marking genes ie: saddle vs. "blanket" vs. bicolor vs. solid, full masks, pigment, cream vs. tan vs. red ect. Basically all things related to genetics that show physical traits in the dogs with dominant/recessive genes studied. Thank you all in advance!
