I started this thought pattern in another thread, and instead of hijacking it, I thought I'd start a new thread.
If color is important in some breeds, such as paints, should it be a deciding factor on whether or not a stallion keeps his gonads? If a breed standard is to have color, such as in Paints, then why breed a Breeding Stock paint when the foal isn't guaranteed to have color? Why have a horse procreate that isn't itself an exceptional breed representative, where color is a requirement?
Now of course I'm saying that there are other factors in play here, such as conformation and all the rest, but color does come into play for some breeds... although it SHOULD be the icing on the cake, what about the points above?
