I am sorry for the late reply, I was deep in another project and let the reply get away from me.
I wish I knew the answer to your question.
But I think the later may be the best answer.
(100% nonvisual het for hypo with a slight possibility of being also het for Albino)
What throws me off is when compared to a Green hatchling; they do look somewhat yellow.
See the new pic comparing a green and the Het for Hypo.
They definitely look different then standard Greens, which I think means they are somewhat co dom.
When I bred Male and Female Hypos I did have 100% Hypos
I don’t know if that really answers your question, what do you think?
