Way awesome I love Spiders
I want to get a pair so bad. Maybe next year.

Kevin & N.E.R.D you guy's rock

Have a white snake that makes fires and spiders and fire spiders!! And white spiders!

It would be nice but I don't think you would be able to get any plain spiders out of it. All the offspring of a leucy from the fireball line should be at least fireballs.

If I had to guess, I'd guess Kevin test-bred/outcrossed his WC Black-Eyed Leucy to a Spider, and the het Leucistic animals look like the FireBalls.

Just a guess of course.

Regardless, looks to be another good looking Spider cross.

You dont think its possible to have a white snake that is also spider? I think its possible to have both genes, of course the white would probably be expressed visually.

WHo knows, maybe we will soon..

It most likely will be possible to have a leucistic that is also a spider but like you say you probably wouldn't get to see the spider part since the leucistic should take away the pigment to make the spider pattern.

However, if it was a homozygous fireball spider then all of it's offspring to a normal would be fireballs. Some (about half) of those fireballs would also be spider but I don't think you could get any that where just spider and not also fireball. Not a big deal since obviously the fireball spider is nice to look at, just not as much variety as your first post.

There is I suppose some slim chance that spider and fireball just happen to be close together on the same chromosome and it might be more difficult than crossing this spider fireball to another fireball and getting 1 in 8 leucistic spiders (that you probably couldn't tell from the 1 in 8 leucistic non spiders short of breeding). The tell tail sign if they where close together on the same chromosome would be that the spider fireball when bred to a normal would tend to produce only fireballs and spiders and no normals for a long time. If they are on different chromosomes you should get 1/4 normal from spider fireball X normal.

That is one of the best Fireball Spiders I have ever seen!!!!

Congratulations!!

But if you produced a leucistic spider, how would you know?

I guess the advantage of mixing other genes, especially dominant type genes, into leucisitc is that you can get neat combos in the het leucistics (like this spider fireball) and also you will get fewer normals along the way. Normally a fireball X normal would be expected to produce half normals. This fireball spider X normal should only produce 1/4 normals in addition to half the fireballs now being spider fireballs.

Per my other post there is some possibility that the spider and fireball genes might just happen to be close together on the same chromosome. This would throw an interesting curve in. If that is the case, then fireball spider X normal will produce (with rare exception) only fireballs and spiders. You would not get the expected 1/4 normals or even the expected 1/4 fireball spiders.
