Yes this animal is not a pin but there is also such a thing as a heterozygous pin. Pinstripe is actually the reason it's more important than ever for ball python people to start understanding what "heterozygous" really means. It does not mean "normal looking hidden gene carrier", it just works out that way with recessive mutations. It also does not mean "half way to another morph", it just works out that way with co-dominant mutations (i.e. a pastel has a heterozygous genotype at the pastel locus, it isn't really correct to say it's heterozygous for super pastel).

As the first proven dominant mutation type in ball pythons we will now need a way to talk about the differences between het pinstripes and homozygous pinstripes that look the same. So understanding that "heterozygous" really means having an unmatched pair of genes at whatever location you are talking about you can see how a het albino, a pastel, and a het pinstripe all have that in common. How they look in relation to normal and their homozygous mutant forms is what defines the mutation type (recessive, co-dominant, and dominant). The important thing is understanding that they are still all hets and follow the same breeding results such as each baby having a 50/50 chance of getting the mutant copy from a het parent.
