Default All Dog Coat Genetics

I posted the German Shepherd stuff, but I thought ya'll might be interested in what colors make the dogs tick...so maybe you can look at your dog and go..oh yeah...he or she has that gene I'll give the Locus name in bold, and next to that the locus symbol, and under that I will place the alleles and their symbols. I think there are variations from dog to dog, like certain loci affect different breeds differently...but this is the general stuff.

I believe (not 100% sure) that when they say wild type they mean no changes made by these genes.

Agouti : A
Solid Black - A
Sable - ay
Grey - ag
Saddle - as
Black and Tan - at
No pattern - a

Albino : C
Wild Type - C
Chinchilla - cch
Dondo - cd (white with black skin)

Brindle : Br
Brindle : Brb
Wild Type : Br

Brown : B
Wild Type : B
brown/liver : b

Cyclic Neutropenia : Cn
Wild type : Cn
Cyclic Neutropenia : Cncn

Dilution : D
wild type : D
maltese dilution : d (usually to blue I believe)

Extension : E
Dominant Black : Ed
wild type : E
fawn : e

Flecking : F
Fleacked : F
Non-flecked : f

Grey : G
Grey : G
Wild Type : g

Grey Points : Grp
wild type : Grp
grey points : Grpg

Harlequin : H
Harequin : H
Wild Type : h

Intense : Int
Cream : Intc
fawn : Intf
tan : Intt

Mask : Ma
Masked : MaM
Wild Type : Mam

Merle : M
Merle : M
non-merle : m

Piebald : S
wild type : S
Irish : Si
Piebald : Sp
Extreme Piebald : Sw

Pink Eye Dilute : P
wild type : P
Pink eyed dilute : p

Powder puff : Pp
wild type : Pp
powder puff : Pppp

Slate Grey : Sg
slate grey : SgS
wild type : Sgs

Ticking : T
Ticked : T
wild type : t

Tweed : Tw
Tweed : TwT
wild type : Twt

White : Wh
wild type : WhW
White : Whw


This is from a farily new book called Genetics of Coat Color and Hair Texture edited by D.P. Sponenberg and M.F. Rothschild.

Again, I think certain Loci affect these dogs differently...either that or the books I was reading on the GSD are a wee bit far behind Oh well, more research for me Hope you all enjoy!

Uhhhhh... lol I have no idea what all this means... I'll go with me old-fashioned "Jenny is black and white" statement.

Would she be this?

"Extension : E
Dominant Black : Ed"

I would have to say Jenny has the solid gene a-a at the agouti, Ed-Ed at extension, and then probably Piebald maybe? That might be what causes the white on her chest

I've not heard of the book but the universal letters for a mask is actually Em, The 'harlequin' is known as the white spotting gene and is sp (with some others for different types of spotting). You also haven't got dominant blac(K) or the K gene!

corona is yellow(her mom is yellow/dad is black)

lol, I just pulled this straight from a book in the Virginia Maryland Regional College of Veterinary Meidicine Library, which is also a research school. I need to find another book on dog genetics, but havent been able to yet

I also noticed that there are some differences between this book and one of the German Shepherd books I was looking at, but since this is more recent I decided to quote mostly what was from here...the German Shepherd book quoted the mask as you said above, but I have no idea where the K comes from.... Do you have suggestions for more books (preferably recent) that have this info? I am really interested it...and I didnt see what is responsible for making the points white. This subject is always changing I think, so its possible that information from the past has changed or the information from that book has changed in the five years its been in print.

As for labs here is what I found =

Black labs are wild type in the Extension Locus, most likley with no pattern in the agouti locus Choclate labs are bb in the Brown locus, and yellow labs are ee in the extension locus. Black labs are the dominant of the three colors.

this is a site for the labradors that I looked up...it gives the combinations. http://www.blueknightlabs.com/color/coatcolor.html

Hope that helps

I am so much better with horse color genetics than dog color genetics.

So if I have a mostly white dog...but with dark brown spots on ears and one big spot on her rump-Whw S?

the brown spots (if they are small like a setters) are most likley due to a ticking gene if she is mostly white with a brown spot it is most likley something in the spotting gene (probably piebald or extreme piebald) restricting the color to that point on her body

Hope that helps some
