I realize we have many new players and the original colour model thread has been lost in the old thread pile so this is a quick summary for anyone wanting to breed for colour.

A gene
A - Agouti
a - no agouti
A > a

B gene
B - Black
b - red
B > b

C gene
C - not dilute
c - dilute
C > c

S gene
S - solid
si - white markings
sp - piebald
sw - pure white
S > si > sp > sw

not dilute colours:
Black aaB-C-
Red --bbC-
Agouti A-B-C-

Dilute colours:
Silver aaB-cc
Pale Red --bbcc
Wolf Grey A-B-cc

Symbols:
X > Y : X is dominant to Y
X- : Any combination of X and any other type equally or less dominant than X.
-- : any combination of types

What would be my best bet to get color with a White bitch? Ifg i bred her to a white dog, would it result in healthy white puppies, or I'm a better to stick with another 'rare' color? Thanks so much.

White bred to White will produce all White pups.
You can also breed to Piebald (any colour) and get a mix of White and Piebald pups, this can be particularly fun because you don't know what colours of piebald your going to get because the white gene hides the other colour genes.
I suggest avoid breeding with other patterns/colours because then you have to deal with carriers and if your not careful you can lose the white gene.

How to use this information:

Step 1 - As much as possible infer the genotype of your dogs

Initially: --/--/--/--

Is your dog Red something (or Pale Red something)?
Yes -> --/bb/--/--, No -> --/B-/--/--
Is your dog dilute (Pale Red something, Wolf Grey something, Silver something)?
Yes -> --/--/cc/--, No -> --/--/C-/--
Is your dog "White"?
Yes -> --/--/--/swsw
Is your dog Black (colour name contains "Black" or "Silver"wink ;)?
Yes -> aa/--/--/--,
Is your dog Agouti (colour name contains "Agouti" or "Wolf Grey"wink ;)?
Yes -> A-/--/--/--
Is your dog Piebald (colour name contains "Piebald"wink ;)?
Yes -> --/--/--/spsw or --/--/--/spsp
Is your dog something And White?
Yes -> --/--/--/si-
Is your dog solid (colour name does not mention white or piebald)?
Yes-> --/--/--/S-

Put the results from these questions together.

Next, if you have any half knowns ("X-"wink ;) left look through your dogs pedigree for any do you know both?
Yes -> do nothing there is still uncertainty for your dog
No -> Fill in the unknown with what ever X is (eg. B- = BB, C- = CC ...)

Step 2 - Take the two dogs you plan to cross: figure out all possible combinations taking one of each letter from each parent and match them to the colour codes above to figure out the possible colours of offspring. The more different colours are possible the less likely you are to get any particular one.

I have a question for working on the Sibe colour pics wink ;)

"Black" = Solid Black... yes?
Like this:
i.oodleimg.com/item/2886017301u_0x424x360f_dogs_in_south_bend_in/?1326446881

Then... does "Red" and "Silver" mean solid as well, without the typical husky markings? I've never seen a husky like this, however I understand that the genetics need to be there.

I just want to make sure I colour them correctly wink ;)

Thanks!

That is correct. Any dog that has the color name and not "and white" is a solid dog in this game.

You will sometimes see small amounts of white on the tips of feet, chest spots and nose/tail tips but these dogs do not have the classic white face, collars, legs and underside of "traditionally" marked huskies.

Some more examples:






The gene that causes "solid" can modify any color so breeding a solid dog to any other dog can result in solid pups in any color the parents carry. It's also dominant which is nice so you don't have to track carriers.

That was probably more info than you wanted but I love color gentics and tend to get carried away ...lol

Thanks!

And no, not too much info at all! I'm actually a biology major and have taken a number of upper year genetics courses (my favourite subject!) so I totally get the genetics behind it. But I just wanted to double check and make sure I wasn't misinterpreting something!

Hey! If any one has the time and is interested- I would like any ones idea on how my actual genome might look like!

She is white or creme with pink paws and nose, blue eyes, and liver pink eyeliner. I assume shes an Isabella white - which would make her a diluted red husky but I am ignorant about dog genes and everything I have found online has been extremely confusing and inconsistent - ilIm not sure how the genes interact but if any one has a guess, you are my hero!

Additionally, how does the oxidized color dilute cr or rr effect other dog breeds? If she had puppies with other colors would they be white, diluted, red, or is it a completely random?

Thank you so much to any one who can help! ??

Did you know?
A conformation dog show is not a comparison of one dog to another but a comparison of each dog to a judge's mental image of the ideal breed type as outlined in the individual breed's breed standard.
