That is not correct.
Bushmaster 2008, Platinum X Platinum breeding produced all Leucistics, which are very similar to the Leucistics branded "abu ivories" by Prehistoric Pets the same season. A name coined by myself.
To be clear the Abu is not a "super ivory", the Ivory, the Ultra and the Abu are all the homozygous version of a platinum. If there were 3 chromosomes as you suggest at that gene location we would see a severe propensity towards malformed animals. Think trisomy 21, and the like.
