So I've had an interesting conundrum that I've been thinking about for quite some time with Sugar to the point that it would be interesting to have her genetically tested in terms of her pigmentation.

So, it's clear that Sugar is more than likely a good example of a dog that carries two recessive alleles on the S locus. It's also clear that she carries the liver alleles for eumelanin.

The only colouration that can be found on her actual fur are some very fine spots on the back tips of her ears, and they are brown.





Now, interestingly enough, if you look at the pads of her feet, she has BOTH liver and "black" spots. I was under the assumption that they could be either black or either liver. What interests me is if these "black" spots are just areas of hyperpigmentation due to the thickness of the skin, or if she really is showing some incomplete dominance between the black and liver alleles. But, you'd think if she was codominant, that black spots would be found elsewhere on her body, and not just on her pads.

See what you think. Some spots clearly are brown, while others are pretty stinking dark.
