Normal X Pastel

[Drew87]

Sup everyone, ok last stupid breeding question haha i know pastel is not dom, or codom, so if i breed my pastel male to my normal female the only thing im gettin is het pastel right ?

[LadyOhh]

No such thing as a Het Pastel. It's a co-dom, so therefore is visual or not. No if, ands or buts about it.

You would get (statistically speaking) 50% normals, 50% Pastels

[ADEE]

your pastel is a codom color morph (where as a spider is a dom pattern morph). there is no such thing as a het pastel. you would get pastels and normals if you bred the two together. hope this helps.

the two post above are 100% spot on

[Drew87]

yea i just read that i didnt mean het pastel but ok so ill get pretty much 50/50 chance of pastels or normals

maybe you didnt see my last post

I think it tends to confuse people when it is said that there is no such thing as a het pastel. It might be more accurate to say that there is no such thing as a "het FOR pastel". A pastel IS a het. It carries one of the two alleles for the pastel trait. Because it is co-dominant, it is a visual het. The homozygous form is, of course, the super pastel.

If anyone tries to sell you a normal looking snake saying that its a het pastel, or het for pastel, run! Since its co-dominant, if its a het, it shows.

A common misconception in the ball python breeding community is that the word heterozygous only applies to recessive traits. Thats just not true. Genetics is genetics. Hets exist with all genetic traits. Some are visible (co-dom and dom) and some aren't (recessive).

As far as dominant is concerned, spiders may or may not be. Nobody has proven that they have a homozygous spider. If its co-dom, the super either hasn't been produced (unlikely), or the spider gene is lethal in its homozygous form. I think thats also unlikely. If its dominant, then there should be homozygous spiders throwing 100% spider babies. I've heard rumors of that, but haven't seen any evidence. So it could still be lethal in its homozygous form. I'm not sure there are many people breeding spiders to spiders. Most are going for combos.

If the results of breeding a spider gives any non-spiders, then the parent spider isn't homozygous. Its heterozygous: a het.

Does this mean I could say my Male Double het for VPI snow is also Het Normal technically speaking?

Oh thats got to be good "Het normal", but what allele(s) are we talking about?

Sorry I just couldn't resist to add confusion and chaos!

Steve,
You beat me to it. Great post.
