I was thinking the other day...please bear with me.

I know a little about boa genetics, but from what I gather, there is a super salmon. Now, it does not look any different from a salmon. What are the chances that there is a super spider, it just has not been bred yet to prove that it does exist. Does anyone know of how many spiderXspider breedings were done to say that there is no super? If there is a super spider, or someone thinks that they have one, I would like to hear about it.

Thoughts,
Jason

NERD did spider to spider breedings rumor has it they produced a homo spider - looked the same as a regular spider. Whether or not it consistantly produced only spider offspring is in question. And Kevin apparently aint talking. I think once it was established there was no super form breeders decided their spiders were best used in new mixes.

Or I should say woblers. When Kevin got his first spider he tried to produce this very creature. He inbred the snot out of them to find it and only managed to produce Spiders with more and more progressive woble heads.

But that is how it goes when you try to prove out a genetic morph sometimes. It doesn't always turn out for the best. That's what makes it fun to try.

I'm reminded of a saying by one or our nations most quotable figures, "Life is like a box of chocolates, you never know what your gonna get."

There is a super, Kevin told Tom Carlton there was a super. The only problem is you can't tell it from the others except when it breeds it produces all spiders. I think Kevin is keeping all his supers and making twice the babies everyone else is.

Super is generally in reference to phenotype meaning that it looks different than the co-dom trait. We are aware that NERD produced a homozygous spider which there were varied reports as to wether or not it consistantly produced all spiders. Tho I guess some people would argue that Super could also refer to the genotype as well.

Yes there is a way to tell if you have a super salmon. Just look at the tell rings at end of the tail and a super salmon will have no black around any of the rings. If it does then its just a salmon.

Thanks for iforming me of that Craig. Like I said, I know little to nothing about boas, I have just seen them listed as poss super salmons so I thought that there was not a visual difference.

It's sorta like the het pied marker. Some people say that 100% hets have markers on their bellies and some have proven hets without the marker. It's a good way to pick them out but not fully guaranteed.

In the salmon boa, there have been some supers that have those rings and some that don't. This is why...most salmons are being sold as possible supers (whether or not they have the black borders). It's because there is no guarantee that the salmons without the black borders will prove to be supers.

But the only way you'd get a Super Spider is if the gene was co-dom, right? I thought the gene has since been proved to be simply a dominant trait, which would mean there is no Super form, right? Thanks -Deb

As far as anything that is actually official the "Spider" gene is dominant in form.

The question now is this, does the Spider carrying two of the genes (homozygous) look just like a normal spider?

Personally, I'm betting that the gene is lethal in the homozygous form 99% of the time, maybe someday there will be a spider that throws clutches of all spiders, but that seems about as likely as a mule being fertile, since Kevin at N.E.R.D. has definitely done enough breedings to determine what exactly has been done, and there would be no reason to hide the fact.

-Dan

Then what you are saying backs up what I was trying to understand; there is no Super form unless you are working with a co-dom trait. As far as the homozygous form being lethal, how exactly would we know? Perhaps the homozygous form and het just look the same.

Does a normal het appear different than a homozygous normal? So how would you know that the homozygous form is lethal in the Spider? The only indication I can think of is if there were a high percentage of slugs or mortality rate from breeding two Spiders together; & at the frequency that would mirror the punnet square percentage of het to het breeding. Am I overlooking something here? Thanks for taking the time in advance. Deb
