Anyone know anything about the banded/reduced pattern line that Ian G @ Outback Reptiles proved to be genetic? I was told that it is co-dom, so what is the super form? Or is it just dominant so far? I'm buying a female from someone local, she's incredibly gorgeous. I thought she would be cool to mix into other projects, thinking a very reduced, banded caramel albino or regular albino would be really neat.

This is the female:

I'd really like to find out more about this project if anyone has info, or has a link to anything Ian G. put online about it.

I really think she's one of the nicest looking genetic reduced animals I've seen and I really want to know what the scoop is so I can work with her in other projects. I think she could make some neat animals.

When you breed a Co-dominant trait to a normal it's a coin toss if the offspring are phenotypically the co-dom trait or normal, but does a co-dom have to have a super show a different phenotype?

>... does a co-dom have to have a super show a different phenotype?

Yes.

A recessive mutant gene is one that shows an effect only when both genes in the gene pair are identical mutants. An animal with a recessive mutant gene paired with a normal gene looks normal.

A dominant mutant gene is one that shows an effect when at least one gene in the gene pair is mutant. An animal with a dominant mutant gene paired with a normal gene looks like an animal with a pair of the mutant genes.

A codominant mutant gene is one that also shows an effect when at least one gene in the gene pair is mutant. But in this case, an animal with a codominant mutant gene paired with a normal gene can always be distinguished from an animal with a pair of the mutant genes.

The "super" is the animal with a pair of the codominant mutant genes.

These are the standard definitions for recessive, dominant, and codominant mutant genes.

Most of the mutant genes in snakes are recessive to the normal gene. Some mutant genes are codominant, and only a very few are dominant to the normal gene.

Paul, it's people like you that make these forums such a great place to visit. I always appreciate your comments and you're spot on when it comes to genetics. Keep it coming!

All the best,

Guy

Did you find anything out?

Je n ,

I would make sure that snake is eating before you buy it . It looks like it needs a few meals . The back looks triangular (you can see the spione clearly ) and the head looks very skinny from the pictures vantage point . nice pattern but make sure it's eating beofe ryou take on a potential problem , best of luck

Not all snakes that have that look are non-feeders or skinny. My albino's spine is prominent like that and she eats very well -- just under 900g at 14 months old. This genetic banded female is less than a year old and 478g at last weigh-in.
