The Super Spider is not visibly distinguishable from the heterozygous Spiders. The only way to know is to breed it to a normal mate...if you get ALL spiders, then you have a Super.

Gee thought they might have a different brighter look.

Will somebody get Nemo!!!! NOW

Now there are:
het spiders
homo spiders
50% poss homo spiders
33% poss homo spiders
What about the price?
Are the homozygous spiders 2x the price of heterozygous spiders?
And how about the possible homozygous spiders?
And will there be a difference in the price for males and females? I think the females will be a lot cheaper because the males can breed with more females and not a lot of people want to breed spider x spider as the super spiders look the same so you end up with 33% possible superspiders.

>>The Super Spider is not visibly distinguishable from the heterozygous Spiders. The only way to know is to breed it to a normal mate...if you get ALL spiders, then you have a Super.

I think there would be 25% chance homozygous spiders from breeding heterozygous spider to heterozygous spider and 50% chance homozygous spider from breeding proven homozygous spider to heterozygous spider. The 33% and 66% only come up with recessive mutations where you can pick out the homozygous and come up with those percentages for the normal looking ones.

But, before we jump the gun, are there some "proven" homozygous spiders out there? I guess it depends on how much proof you need as you could get all spiders from breeding a het spider to a normal if you where lucky enough.

Statistically, 25% of the clutch from two het. spiders would be normal. Therefore, 1/3, or 33% of the spiders would be homo.

Right on, JakeM!

And 50% possible homozygous spiders would come from a homozygous spider x heterozygous spider mating.

Paul Hollander

so all this is what I figured out already.
I don't know if there are homozygous spiders, but if there aren't... how do you know that homozygous spiders look like heterozygous spiders???? So there must be homozygous spiders.
Now about the price.......
Please reply.

Kevin at NERD posted on here that he's bred spider X spider repeatedly, and never gotten any "super" morph out of it. Therefore, he assumes it's a dominant, and not a co-dom, trait. You'd probably have to talk to him about the price as I doubt there are many others with a pair of spiders.

Jake

The price is relative to how much people trust he who declares an animal a "super"...if Kevin @ NERD (who we ALL know has worked darn hard to establish his reputation) says it's a Super Spider, I'd pay at least 150% of what I'd pay for an unknown specimen (i.e. could be hetero, could be homo).

Sorry, I did screw up. Due to the 25% normals being picked out from a het spider X het spider the remaining ones would be 33% chance homozygous spider and not 25%. Can't forget about those normals!

Of course all of that assumes that there can be a homozygous spider.

Just playing the devils advocate here but I wouldn't assume it's completely dominant just because they haven't seen a visible super spider yet. Sure it's possible the homozygous spider has been produced and looks just like the heterozygous spider but until one is bred to a bunch of normals and produces only spiders it isn't proven. These things take time and I don’t suppose there has been enough time for this new morph for anyone to know for sure yet.

The other two possibilities I see are:

1. No one has been lucky enough to produce a homozygous spider yet. I'm not sure how many spider X spider crosses have been done yet and how many babies where produced but maybe the dice just haven't rolled right yet.

2. It's possible (although I don't think likely and I certainly hope not the case) that it could be co-dominant and lethal when homozygous so homozygous spiders never hatch. Again, I don't think this is likely but it's always a possibility with "dominant/co-dominant" mutations and people don't seem to think of it. Just like the possibility that two recessive mutations are close together on the same chromosome making them difficult to combine it's an unlikely but possible thing that is one of several possibilities to consider.

Not only that, but could you imagine the opportunities for ripping off people on a homo- vs. hetero- basis? I mean, like the recessive het-rip-offer's aren't bad enough!
