normal and spider... what will the babies be?

I currently have a normal male BP. I'm looking into getting a female spider and raising her and my male until they are old enough to reproduce. If they did eventually have offspring would half of the babies be spiders and the others normals? Or would they be something different? I'm doing research on breeding and everything, as I'm still pretty new to it. :confuzd:

50% spider 50% normal

ok, that's what I figured but I'm still pretty new to snake breeding. Are spiders a good investment?

I love Spiders they are one of my favorite's. Spiders are the gateway to loads of cool morphs, Bee, Lemon blast, Albino spider and so on. Since they are co/dom they will get like pastels in that they will steadly go down in price but will level off. They are a great morph to start breeding with. Now if you get a female it'll be three years till she can breed by then spiders will be like pastels get you a male spider find a breeder size female and breed in one year to see a quicker return on your investment

Ok so you get 50 %visible spider and 50 % normal....would the 50 %normal be 50% het for spider...then could you breed back the 50 %het to the spider and the normals would be what % het for spider....sorry to jump in on this. I also am trying to learn and understand the genetics of breeding.

No, there are no hets. To be spider they only have to have one copy of the gene. They either have it or they dont. The non-visual babies are 100%normal.

To understand a little more about genetic I would recommend you to visit Mark Mandic website he made the genetics pretty easy to understand.

What Ed really means is that each snake has a 50% chance to be a spider and a 50% chance to be a normal :D

Thanks for that link! Looks like spider would be the way to go.

Spiders are AWESOME :D

Oh man the hetero, homo, identical, non identical ,allels, what ever just totally threw my for a loop. Will have to try reading through when I am not so tired LOL

Genetics is a complex and fascinating subject.


It is one of the main reasons why I am in this business.. :love:

It all falls into place. Just keep researching. As long as you stay with basic stuff, you are okay without knowing alleles. It is easy when you are dealing with 100% hets and visuals but when you start getting into breeding 50% possible hets to 25% possible hets and double hets(1 snake heterozygous for 2 genes) that it gets confusing

LOL Lost me again. I am going to spend the next couple of days trying to read up and pick Ladyohs brain!:D

Man, sometimes I hate being so darn picky! :oops:

Spiders haven't proven to be Co-dom yet, as far as I know - so they would be classified as dominant, not Co-dom (having a super form).

show off.. :D sorry if I confussed anyone. Robin is right they are Dom not Co-dom

Is this true? Does it not depend on whether or not it is a homo or het spider? (i know they look the same) but if you mix

het spider X normal you would get 50% het spider and 50% normal
homo spider X normal you would get 100% het spider

Isn't this right? (http://www.ballpython.ca/what_get/dominant.html)

Yes, if there is a homozygous spider it would produce 100% heterozygous spiders when bred to a normal for spider because the homozygous spider would only have the spider version of the gene to give so would give the spider gene to each offspring. A homozygous spider is assumed to look like the heterozygous ones we have seen so far but given the lack of public breeding data proving a homozygous spider 7 years into the cb project I'm suspicious that the combination may not be viable.

If we do eventually prove a completely dominant mutation it will be even more important to start using the true meaning of "heterozygous" (having an unmatched pair of genes, not necessarily normal looking like with recessive mutations) as a way to distinguish between the two genotypes having the same mutant appearance but producing different breeding results.
