I'm thinking that the word "dominant" can be used in different ways.. (which of course it can)
"dominance" as a mode of inheritance vs. dominant in the sense that a superhypo is dominant because it will produce all hypos.
I'm starting to remember my highschool genetics.. but for the sake of being sure, I'm going to try and repeat what I believe you just said.
Dominance (Dominant mode of inheritance) places the emphasis on the need to have the dominant allele to receive the trait. Recessive(Recessive mode of inheritance) places the emphasis of needing two recessive alleles to receive the trait.
hypomelanism is passed through a dominant mode of inheritance.. all the boa needs is one dominant allele from either parent, but Albinism is a recessive mode of inheritance which requires that the boa receive a recessive allele from each parent in order to inherit the trait.
the importance of "het" when referring to a recessive mode of inheritance is different than when referring to a dominant mode of inheritance. the "het" is REQUIRED to produce an albino , but the "het" is not required to produce a hypo. (I think that made sense)
which is why I am now going to take a HUGE risk and go back to my original thought that a hypo het for albino is in my opinion not a true "double het" - unless you wanted to say that a hypo het for albino is a double het for Supersunglow.
but - of course I could be completely wrong also.
