Pituophis catenifer morph help

mkv Nov 29, 2010 11:38 AM

I bought 2.2 Pituophis catenifer annectens from a guy.
He told me one of the males were super hypomelanistic and the other 3 were albino. Since I dont know how the genetics of Pituophis sp. morphs are I need help.

Is hypomelanistic a co-dominant gene that can produce "super"-form of hypomelanistic?
Also, is albino a simple recessive gene?

Below a few pictures, help me identifying morphs.

Albino

The other albino individual

Breeder pair, male "super hypo" and female albino

Hypo(?) juvenile from the "super hypo" X albino-cross

Albino(?) juvenile from the "super hypo" X albino-cross

Help me figure this out for future breeding.

Thank you,
M

First let me say those are some awesome animals. The super hypo is a screamer. OMG.

Second to try to go into the whole genetics thing is more than can be covered in a thread. That being said here are 2 links you might find very helpful in explaining genetics and how they work.

This one is a very good easy to understand explanation of genetics.

This one is the genetics wizard. You can input the traits of your breeders and it will give you the potential outcome of your litters. Keep in mind even with the best information you may not end up with the ratios that this will output.

Now for the pics of your babies. The first one looks like a patternless in that picture not a hypo. Can't say for certain but I see no pattern whatsoever.

Hope this helps in your quest for info.

Hi and thank you.

I have some knowledge about simple recessive, co-dominant, dominant etc genetics. However, I dont have any idea how Pituophis catenifer ssp. genetics work. Are their albino-gene simple recessive as it is in boa constrictor ssp.? Same with the hypomelanistic gene, in boas hypo is co-dominant gene.

I bought my male as super hypo, which makes me beleive that hypo-gene is co-dominant. Am I right?

the super hypo you have looks to be a T Positive amel. With some of pits the term is interchangeable.
the gene is no co-dom but recessive. my take is that the 'super' tag refers to him just being an outstanding example of the line.

i believe striping is the only co-dom gene in catenifer.

of course, i could be wrong.

hope that helps some.

the animal pictured is a T Positive san diego.
