Breeding hidden true recessives.

[Barbara Collazo]

Well--this is all really helpful, but not germane to the question I asked, which was, when bringing out a hidden recessive, why is it more useful to use a more dominant trait than to use one that's only a step or two away? The post that prompted my question said that it was harder to get Snowshoe Cream out from under a Foxie S&P than from under Siamese Seal, for example. I don't see why it's harder--the probabilities are the same.
