I had the same thing happen, but it was outta the Parker line... Most Parkers will be blk or brindle, but my 1st breeding from pups I raised produced 3 yella/red pups outta 9. At the time I did not own any yella dogs, nor was my gyp around any to my knowledge but due to this being such a rare occurrence I went ahead and had 2 of the 3 yella pups DNA tested and they came back pure Parkers. Then the 2nd litter had 3 yellas outta 7 pups. Maybe its the Mt Curr coming out in the Parker line??? Surprising to say the least!!!
if the parker parents are black and we know that the color black is dominant over red, so this means that both parents carry one dominant gene for black and one recessive for red...so the litter turned out 66 percent black and 33 percent red...if one parent carried double black genes or even both parents, then all the pups would have been born black...that one is pretty easy...this also means that either black dog can be bred to a red dog and there would be about 1/2 the litter red because in this breeding it has been proven that both parents are carriers of the red gene...
