I've always been interested in the genetics of koi.
I have a marusume showa from toshio that as a tosai would have been called
kindai. Equal amounts of black red and white. This winter black took over and i was sorely disappointed. Now that spring has come the black is all dropping away past the tosai stage amount. I have a feeling his black was developed from matsunosuke sanke, the better ones do this "trick" as nisai.Then slowly come back in the better ones. With Sanke the spot in question is inevidentably the important shoulder sumi. So will be interested in seeing what happens to showa.
I have also seen other examples of goshiki based koi that develop Ai and then loose it. I'm not sure what it is, but I see more of it in this color variety than others. BTW this spring I will be getting tosai goshiki from Mat at Nisei koi farm to raise and study. Like so many of my favorite color varieties, this one also has it's roots in asagi.
