from Angel's explanation, the babies get half of genes from father and half from mother (all that talk about left and right columns, remember?).
Black is dominant over Buckskin (hence why it was a black baby), when breeding you need to look at gene power as well, so that you know which one is going to show up if its included in the pair of genes. Piebald is a pattern, so I assume that both parents had a pattern other than piebald in their gene pool.

So in the genetics libraries where it indicates genetic power, *that's* the deciding factor in the dominance? I thought it was just a scoring tool used for the leaderboards and the dominance was just an RNG coin-flip to see if it was the left or right column which attained the dominant gene. With the frequency percentage measuring the rate of occurence in wild-caught specimens to give a gauge of rarity.
I had just bred my striped blue cockatrice who was carrying a dilute and green with a full dilute, blue dilute stud who was carrying orange - the child is indeed a blue dilute. I've yet to fully uncover the genetics of the little guy, but if what you're saying is true then it would be safe to assume that the child didn't inherit the striped gene (which has a higher GP) of its mother?
Your theory at least makes sense with the blue coat, which if the punet square is still applicable only has a what? A 25% chance of being dominant-recessive blue? There's still a 50% chance this child is still a carrier for another color. This makes it increasingly unlikely that blue would win the coin toss to be the dominant trait unless it would present dominant because of its GP advantage over green and orange.
This would essentially mean that rarer coat colors like white, black and silver would *have* to be dominant-recessive to present as a phenotype.
What doesn't make sense though is that the frequency percentages don't add up with it. If blue is dominant over green, why are 66% of cockatrices green versus only 16% are blue? Heck, I've seen a lot more white cockatrice (5%) than orange (20%) - at least on the market.
