Boa morph question

Breeding a male motley boa with a het hypo female, what do the geneticists think the offspring would be?

Thanks

Ok I have been out of bci genetics for a bit but my understanding is both hypo aka salmon and motley are co-dom traits.
So firstly you cant get a het hypo, it either is or it isnt.
So your offspring if
- normal x motley would be 50% motley, 50% normal
or if
- hypo x motley would be 25% hypo motley, 25% motley, 25% hypo, 25% normal.

Someone please correct me at this late hour if the wine is talking rubbish

Actually, hypo (AKA salmon) is a dominant mutant gene rather than a codominant mutant gene. But the expected breeding results in the mating above are the same: 25% hypo motley, 25% motley, 25% hypo, 25% normal.

A het albino boa has an albino mutant gene paired with a normal gene. In the same way, a het hypo boa has a hypo mutant gene paired with a normal gene. The albino mutant gene is recessive to the normal gene because the het albino boa looks like a normal boa. A het hypo boa does not look like a normal boa. Therefore, the hypo mutant gene cannot be recessive to the normal gene. The hypo mutant gene is actually dominant to the mutant gene.

Most of the hypos in the market are het hypos. However, if the original poster's het hypo looks normal instead of hypo, then the snake is a normal. It would not be any type of hypo.

Thanks guys!

I'm not 100% sure that my female is a het hypo as I didn't see the parents, it's what I was told when I bought her & some of her siblings were hypos. She's a very pale grey with a faded pattern on her sides & the salmon colour is getting stronger & brighter on her sides & belly.

Here's a recent pic


To be honest, I'm not overly fussed if she is or not because I think she's a little beaut & she'll produce some stunning babies when old enough! Male motley I'm picking up next month.

Thanks again for the help!

I thought hypo was a co dom and super hypo/salmon the dominant form.

One thing is for sure --- she is an absolute stunner!

She is a very clean and well coloured individual. She is however NOT a hypo. If she is a 'hypo sibling' she is actually a 'normal'

(although if she was a 'salmon sib' AKA the sibling of a line of hypos that have been selectively bred to be more peachy coloured) then she may well (and does by the look of the photo) have same salmon influence.)


Stunning snake and will make some super looking motleys!

Cheers

Still disputed. Many 'super hypos' or 'homozygous hypos' have a much cleaner look and a further reduction in pattern to het hypos but many breedings in the states have shown that not to be 100% definitive and many people are now saying that it is not possible to tell a heterozygous hypo from a homozygpus hypo until you breed them....

Thanks Andy

Yeah she's a beaut, I knew I wanted her as soon as I saw her!
