oh so it means het! they got 1 male and 1 female heterozygous for albino for 500£ Im seriously might be thinking about this!My googles not working atm so I can't link you to a site if you type "heterozygous definition" into google some sites will be able to tell you what it means. It's all to do with genes, alleles and that sort of thing.
I think basically it means that the snake has the genes and stuff for a certain morph but it doesn't have the appearance but it affects the appearance of the babies if they breed.
So if you have 2 normal corns and ones het for something then the babies wouldn't look like normals.
