if you breed a anery girl, to a het hypo male, what are the results? Is it a normal looking clutch, with 50% het for anery, and 50% double het?or? Has anyone succeded yet breeding double het together?

Cheers

The babies will be 100% het for anery and 50% het for hypo, but yes, they will look like a wild type.

If I understand what you intended, you are correct. Typical accepted naming when dealing with genetics is a fraction to describe the qty of babies and a percentage to describe the odds of having a specific gene.

So, correct way to state the outcome of Anery bred to het hypo is...

all - Het Anery 50% het Hypo. (since they all look like normals and you can't tell them apart)

Hope that helps!!

LOL, to many snakes to list, last count:

20.21 BCI
And those are only the breeders

lots.lots.lots feeder mice and rats

yeah cheers that was what i was getting at. Has anyone done many of these breedings before? And is one more dominant than the other at all? Also at any time with breedings the morphs, is there any differnce with what the male and female are ? Ie which is the het, or recessive. Still new and confused about genetics.

1.2 BRBs

On the way if all the shipping works
0.1 Anery BRB
1.0 66% poss het anery BRB
1,1 het hypo BRB

Hi Dave,

I personally have no evidence either way, but I don't think there is consensus among the experts that the anery mutation is simple recessive. Just something to be aware of.

When you say "is one more dominant than the other", what do you mean by that?

Thanks,
Ed

One trait cannot be 'more dominant' than another. If an animal is homozygous for both anery and hypo, meaning the genes express both traits, then you get a ghost. Anery produces no reds, Hypo produces no blacks, both mutations produce neither pigment.
Hope that helps!

Agreed except, mother nature has more than one position for her "color switches", not just on and off!!

If both the anerythristic trait and the hypo trait are simple recessive traits then you would be exactly right. The Lockwood Hypo trait is proven to be a simple recessive trait but we do not yet know enough about any of the anerythristic bloodlines to say for sure that they are simple recessive. None of the anerythristic lines seem to be co-dominant but there is the possibility that at least some of them are influenced by more than one genetic mutation. This would help to explain why they have been so slow in being "proven" through breeding trials. All sorts of combination morphs are coming some day in Rainbow Boas but so far it has all been much slower than it has been with other species.

I thought that was what you meant.

To date I do not believe there has been a double recessive morph produced - Hypo and Anery in the same BRB.

Mike Lockwood and I believe it was Robert Seib have produced double hets. Mike is waiting one more year before breeding to allow them to gain more size. Unknown what Robert is doing.

Since they have not yet been produced it's also unknown if one trait will have more of an affect than the other. Still in the early stages of morphs in BRB's.

I believe it makes no difference which of the animals is homozygous vs heteroztgous just that each carries at least one recessive gene for the trait in order for some of the offspring to show the trait.
