Pastel to Granite

[gkoserjr]

What would you get from breeding a Pastel (co dom)and Granite (dom ?) ?

[DoGood]

each egg would have a 50% chance of being pastel, and a 50% chance of being pastel-granite. I think....

[gkoserjr]

Thanks dogood...I am new to thiswhole snake genetics thing and had no idea what you would get when breeding a co dom to a dominant

[LadyOhh]

WELL....

If they Granite is Dom, then all the animals would be Granite, and 50% of those would be pastel.

I think at least one line of granites have been proven to be co-doms. Either way, a heterozygous granite x heterozygous pastel should produce 25% normal, 25% pastels, 25% granites and 25% granite pastels.

That's incorrect. Assuming the dominant animal isn't a homozygoat, the numbers above are correct. A spider is a dom trait, but breeding a spider to a pastel doesn't give you half bees and half spiders. You will always get the 25% rates across the board for all four possable phenotypes when dealing with dom or co-dom traits.

I stand corrected.

My real question is, what line of Granites out there are dominant?

[gkoserjr]

This was in the hunters guide to morphs posted on this site.
Genetics: Most Granites at this time are not proven or not genetic. Some have proved out to be Dominant, and we are waiting on 2 lines to see if they are Co- dominant ( Waiting to find out if there is a super form) ....thats why i put a question mark on my original post, because i wasnt sure myself

[LadyOhh]

The only line I know of that is co-dom is Ralph Davis's.

Other than that, I'm not aware.

Camlon has a line, but I am not sure of the genetics behind it.

so then reguardless of what morphs if you breed a co dom to dom
then you would get 25% across the board...is this correct?
And co dom to co dom should be 50 - 50

It has nothing to do with dominant/co-dominant, it's about heterozygous and homozygous. Two animals that are heterozygous for two separate genes will produce 25% each of normal, het for gene A, het for gene B, and het for both A & B.

Dominant, co-dominant, and recessive speak to the nature of the gene itself, and only deals with the way the gene expresses itself in each combination.

Dominant - Both heterozygous and homozygous look the same -- neither appear "normal".

Co-Dominant - The heterozygous and homozygous versions look different from each-other -- neither appear "normal".

Recessive - Only the homozygous version appears different -- heterozygous animals look "normal".
