The genetics really function the same way however it get's tricky with a few mutations that can be either recessive or dom. You have the issue with hypo and aneries as well.

Lemon Hypo is Dominant

Evans Hypo is Recessive (Evans Hypo is really a T+ Albino in case you weren't confused enough)

Then there is the True Hypo recessive also

Those are not compatible.

your friend really has no idea on what line he is working with?

So if your male is a Lemon Hypo and the female is Het Hypo you would get some lemon hypo 50% Het Hypo as well as some 50% het hypo
