Bumblebee x Cinnamon

[Kodieh]

So, my wife really wants a Bee and I'm dead set on a cinny. I was reading up on the pairing, and the percentages break down like I thought they would. Except that there's the 12whatever percent to still hit normals in that clutch?

However, I was pleasantly surprised to learn (and I hope it's correct) that you have the same 12whatever percent to come out with pewters, haha.

So, my question is why would I be able to still hit normals with three co-dom genes?

The only way to not hit normals (percentagewise) would be if one of the snakes had a super in it (super pastel,BEL, super cinny).

You need to have a dominant gene in order not to hit normals.
Co-doms (or incomplete dom) will throw normals because they're not dominant traits. But more genes you have in play, the chances of normals decrease (theoretically).

Example:
Lesser Black Pastel Pinstripe can render normals.
Bumble bees can have normals because it can donate a pastel gene or a normal gene. A spider gene or a normal gene. And a Spider Pastel gene.

But a Super Pastel Spider will render at least all pastels. Super Pastel is the homozygous form of a pastel. Pastels can be seen as a visual het of Super Pastel.

Thats one of the ways, not the only way though.

When breeding non-allelic co-dominant genes with no supers involved, generally the odds of hitting a normal are exactly the same as the odds of hitting the all-in-one power morph.

So, for a bee x cinny, the odds of of hitting a simple normal are precisely the same as the odds for hitting the pewter bee...

In plain terms:

Each parent has their DNA unzip like a zipper and only half goes to the baby. It combines with half of the other parent's genes. There are some genes that go across both halves of the zipper (dominant) and some that require both halves of the zipper to have the trait in order to be able to SEE the difference from a normal (recessive). Pastel, spider, and cinnamon are all co-dominant, meaning that you can see when the gene is on one half of the zipper, and they look different and more 'extreme' or 'super' when it's on both halves of the zipper. It's possible that you get the 'normal' half of the zipper from each parent in this situation.

Hope this didn't make it MORE complicated...


... and yes, I realize there is a debate about the Spider gene. All that's important here is that a snake that looks like a spider has a 50% chance to pass that on.

[LotsaBalls]

Homozygous = 100% chance to pass to offspring.
Heterozygous = 50% chance to pass to offspring.

Nuff said.

Solution, get a Killerbee and a Cinny! or a super cinny and a bee. either way no normals.

Co-doms (or incomplete dom) will throw normals because they're not dominant traits. But more genes you have in play, the chances of normals decrease (theoretically).

if it is homozygous, it will not throw normals, being dominant or incom/co dom has nothing to do with it.

there is also situations where there are two mutant alleles sitting on the same locus, so you get one mutant gene or the other.

to answer your question OP, this is why.

Bumblebee x Cinnamon Punnet Square. Put down each combination of genes each parent can give, the bumble bee can give pastel and spider, just pastel, just spider, and none. The cinny can give a cinny gene and none. As you can see there is a chance for both parents to give no mutant genes.
