"Albino" is a recessive genetic trait...an "albino" ball python is homozygous for amelanism, which means it expresses it visibly...Take your homozygous amelanistic ball python and breed it to a normal ball python, the amelanism gets passed on to all the babies, but in a heterozygous form...simple terms, they are all carriers of the trait, they just dont express it homozygously (I'm slaughtering simple genetics here, but the gist is right)...
