It would be true if the animals are both true albino. In my mind there is only one true albino form. The others that people call albino, just have a dilution gene such as the one that makes a black lab chocolate. There are those that may think a chocolate lab is albino, but it is not( one may argue the T pos and T neg aspects of albinism). If you take one of those so called Ivory tortoises and breed it to the true albino that Ben has, the offspring would be normal. They would be het for albino and het for whatever gene causes the ivory. The gene that causes Ivory is a dilution gene that lightens color. In the second generation of Ivory to albino, you can end up with something they call snow in the trade. The dilution gene of the ivory will remove the remaining yellow pigment of the albino creating a startling white animal.
Providing that at least one of the snappers is a true albino, and the other is a dilution gene carrier(which is what I think they are offering) the results in the next generation would be the same. you would get normals, albinos, dilution gene carriers, and snow(albino dilution gene). This may not work in all animals I'm afraid. Sometimes when a gene is made up of two markers, the gene replicates a normal replacement of the sport gene. You should get at least 6 % snow eventually if you follow the laws of genetics. If all depends on how weak the sport gene is.
