Heterozygous its a genetic thing. Like a ball python can be albino. or Heterozygous for albino. An albino and a normal non HET will produce HET animals but no actual albinos. Two hets will produce some albinos some hets and some normals. An albino and a het will produce hets and albinos. Animals can be het for more things than albinism. Humans can be het for blue eyes. Hope I helped
