What do you guys think would happen if you bred an amel aztec with a carmel? how would the butters turn out?
If you breed an Amel with a Caramel, you won't get Butters immediately. The first generation will be Normal het Amel & Caramel.
If you breed two of those Normal het Amel and Caramels together three years later, then (statistically) 6.25% of the hatchlings will be Butter.
If the adult Caramel has no Motley in him, then breeding him with an Amel Aztec will just produce normally patterned offspring with a Motley het (think Aztec is just a selectively-bred form of Motley, but happy to be corrected).
If you add that into the mix for the second generation breeding, then you have a 1.56% chance of producing a Butter Motley, which may or may not show Aztec characteristics.
A pretty poor return for six years' work, unless you're really, really into Butter Aztecs.
