I went to WOBP and tried several matings.

Pinstripe x pinstripe. Both had a pinstripe mutant gene paired with a normal gene. IWOBP results were 1/4 normal, 1/4 pinstripe, and 1/2 pinstripe. The correct result is 1/4 normal (2 normal genes), 1/4 pinstripe (2 pinstripe genes), and 1/2 pinstripe (pinstripe mutant gene and normal gene).

I also tried a het albino x het albino mating. Results were 1/4 normal, 1/2 het albino and 1/4 albino. IMO, the correct results should have been 1/4 normal (2 normal genes), 1/2 het albino(normal-looking, albino mutant gene and normal gene) and 1/4 albino (2 albino genes).

IMO, there was no difficulty calculating hets. But there was considerable difficulty expressing the results. There was also the continuing belief that a heterozygous snake must look normal, which is false.

WOBP does not express heterozygote probabilities (66% probability het albino, 33% probability homozygous pinstripe). But that is okay. Doing it or not is a matter of choice.
