Breeding Rarity (br) factors in the difficulty in breeding rare Coat Colours. Breeding Rarity is always factored in after the Breeding Pair (bp) equation has been applied. Rarity (r) represents the number next to each coat colour in the Colour Pyramid.
Subsequently, this results in rare Coat Colours being more difficult to breed as it is proven by the following Breeding Rarity (br) formula: br = [r³] / 1000
Coat colour variances are possible with breeding. We have, however, compiled the following two examples to illustrate some possible outcomes.
