Posted: Mon Dec 12, 2011 11:35 am Post subject: Colour genetics question please
Please can someone give me a nudge in the right direction as to what colours could come out with some hypothetical breedings please. I would really like Maple to have some yellow pups if not all yellow, but I am having trouble finding a stud dog that I really like the look of.
Maple is dark yellow, her Dam was black and her Sire was dark yellow. Pups were black and various shades of yellow.
Potential matches for Maple:
Maple to a black dog = all black pups?
Maple to a black dog carrying chocolate = would this create some dudleys? (not my aim).
Maple to a black dog carrying yellow (cant find one of these) = a mixture of black and yellow dogs maybe.
Maple to a yellow dog = all yellow dogs? is it that yellow dogs cannot carry black as black is the dominant colour.
What would be the best match colour wise to produce mainly yellow pups please. This is one of the things that although I 'think' Ive got a good idea of what I need I need to check.
A black dog carrying yellow would likely produce better pigmentation. A yellow to yellow "might" be fine, but black carrying yellow would be pretty certain to produce good pigmentation. (But of course might not produce any yellows, or a yellow of the sex you want.)
For my part I am not keen on yellow to yellow because I do like to see good pigmentation.
Brilliant, thank you both so much, you know when you are pretty sure that you have something right in your head but you just need to check Sprocket is in to be neutered today and my mind keeps wandering.
Maple to yellow - all yellow.
Maple to black carrying yellow - some black and some yellow maybe.
Just got to find one now that is suitable, bit like looking for the proverbial needle in the haystack.
Coincidence! Janice emailed me days ago on it, and I was literally answering by email (finally! Sorry!) as the thread was being filled, so thats good! Mad as in crazy, not as in unpleasant! better get it twice than not at all!

You can / do get good pigmentation from yellow to yellow matings -
The experts "across the pond" told me there is absolutely no bearing on either eye colour or pigmentation from the yellow gene - and that in fact, they are from genes not as yet isolated to be able to test for. (The question was triggered over a potential yellow with black pigment to chocolate carrying yellow mating and some feedback I'd had from others).
The only thing they would confirm impacted on pigmentation (i.e. what we already know) is that when chocolate sits on both sides, you can get liver pigmented yellows.
I've also been talking to someone else whose genetics knowledge far surpasses mine who believes that the presence of chocolate in a yellow with black pigment can impact on how fast the dog loses it's black pigmentation.
This is my boy from two generations of yellow to yellow breeding (both grandfathers carried chocolate) - and Clover whose sires parents were both black
At the same age as Dylan is now - Clover was getting pulled up on her pigmentation in judging critiques and although I haven't colour tested her - the chances of her carrying chocolate are incredibly slim.
Clover has two black grandparents on her sire's side (and a quite heavily black sire's side of the pedigree) - in contrast Dylan has yellow parents and grandparents.
In contrast, Clover's litter sister has superb pigmentation as do her half siblings that I am aware of (same dam) - it seems a waste to test if she does carry chocolate as she will never be bred from - but would certainly add weight to the theory if we knew.
Sorry OP - gone somewhat OT - but just had to point out that Y / Y can (in my own experience) have good pigmentation.

Unless the black dog also carried yellow, then all your pups would be black carrying yellow and some also carrying chocolate.
I know you can get good pigmentation from yellow to yellow Sue, that was why I wrote <"might" be fine> But so often you dont, which is why I dont like it. OK, it's only one facet to consider, and I've owned yellows with poor pigmentation, Beth for one, but all things being equal I prefer good pigmentation.
