Color question in ACD's

[quote="raknrydr"]I have a Blue female out of blue x blue parents,2 blue x 2 blue gparents , then 4 red ggparents x 4 blue.
My male is Red out of blue x red parents, 2 blue gparents x 2 red gparents , then 4 red ggparents x 4 blue.
This is just the first 3 generations, I have had 2 litters of puppies and I have had all red except for 1 blue puppy.
I know red is suppose to be the dominant color in ACD's but I have seen people bred 2 reds and get 6 blue & 1 red pup in the litter, so why do I keep getting majority red pups ? I guess it is just the individual genetics of my male and female ? Will I always get more red or is it just the luck of the draw on each litter as to how many red or blue they throw?[/quote]

Keep breeding. You say you have a blue female. She is (like all true blue's) going to be homozygous for dillute: dd.
Your red male is obviously not homozygous for blue, but should be hetrozygous Dd. You have a 50% chance (no higher) of getting dd blues out of that combination, but on the bright side: all pups should be blue carriers. It is luck of the draw here. I have bred identical combinations with very different results per subesquent litter. So just keep trying. ;)

Isn't the 'blue' here a sort of roaning, i.e. black and white hair mix so genetically black or black and tan based not true dd?

Yeh I'm not sure I understand the DD connection either? Blues are black (ACD)roans and reds are what some breeds call a clear sable (with the ACD roan), so still black based but with whatever dog people call the agouti gene?

What they call blues are often tris too so another form of agouti?

(I have even heard of of true ee red heelers, but pretty uncommon I think, and look pretty much the same as the 'sable' red roans)

So yeh red and blue act the same as bay and black?

But anyway yes keep breeding and the odds should go in your favour eventually!!! :lol:

Trouble is some dogs are dominant black and some are recessive 'self' black. My friend has a sable crossbreed dog whose mum was a black and white border collie and dad was a black Groenendal. Litter was mostly black with just two sables. Not sure about the red genetics- some yellow/red dogs are ee but I don't think all yellow/red dogs are, some are probably A- variants?
ETA and yes it could be just random chance, you would need to breed upward of 100 litters with parents with the same genetic makeup to be sure of a pattern.

Here is a article on ACD color if it helps, http://www.ar.com.au/~norclark/acdcoat3…" onclick="window.open(this.href);return false;
I need to have this color stuff broken down into terms I can understand and since the article is to technical for me but not for some of you, thought you might like to read it.

Here is my female.

Here is my male.

*sigh* My bad. Every breed has its own teminology, often for very different things. Correct labeled blue should be dd, and I failed to cut through the breed terminology. :shock:
Let me try this again then. :oops:
'Ay' yellow the red for your male.
'at' black and tan (pattern like dobermanns, and rottweilers) is your female.
On the agouti locus, the order of dominance it Ay, aw, at, aa.
The male must carry an Ay/at since he did produce a 'blue'. But the female is most likely at/at. You are still looking at the luck of the draw here, but obviously his 'clear sable' red is dominant over her 'black and tan' background. White pattern goes over the top of the backround, just like it does in horses.

Oh cool, I actually understood that! :D

And so did I, which is kewl . I can understand equine genetics, but the dogs blow me away :hammer ....and we won't EVEN begin to talk felines... :rofl
