ok so the Albino BP is a recessive animal this means that when bred to another non albino snake the offspring will not be albino visually but they will carry the gene (this is called heterozygous or het) be breeding the offspring to an albino you can produce visual albinos again
so going with the albino pin
Genetic Wizard 3.0 calculations by
Notice how all of the offspring are het albino
so now you have a few options (in both cases you select a pinstripe het albino)
