simple solution. Outcross whenever possible. Because of the price of albinos and hets when they first became available there was quite a bit of breeding back to a parent. Albino male to as many normals as you have, keep the females, raise them, and breed back to dad to produce albinos. No problem there, it's a standard breeding strategy. The problem MAY come up when the offspring are sold in pairs and bred to each other. When buying albinos and hets it's best to ask about the history of the breeders. Although your buying from two well known and trusted breeders, they may be working with the same stock. Most breeders will agree that they have greater success when breeding albino to het then if they breed albino to albino.
