Spider question

[DC Reptiles]

Can siblings from a spider produce a spider if the siblings would be bred back to each other? I was talking to someone today and they told me this is true but I had never heard of that and I was curious if it was true or not?

[llovelace]

no, they can't

[DC Reptiles]

so with them being normals from a spider they wouldn't carry any of the genes? Just want to get my facts straight

That is correct. Either it is a spider or it isn't

as i understand the genetics of a "normal" (normal meaning not carrying any other genetics) spider being co-dom you shoud get 50% spiders and 50% normals. the normals are just normals / non hets. Kirk

see thats what I thought with it being co-dominant but the guy I was talking to today tried telling me they could produce spiders. Thanks guys!!

Wrong.. Sorry

Spiders do not yet have a super form. not proven unless it's changed recently.
A spider to a normal would give you 25% spiders

and even a spider to a spider isn't guaranteed to produce 50% spiders.

Actually a spider to a normal will produce 50/50 odds. A spider to a spider should produce 66% spider 33% normal because the evidence is weighing in on the side of homozygous lethality. (Otherwise it would be 25/50/25 normal/spider/super assuming each parent has one spider allele each).

Spider is a dom*(sorry dom) there has yet to be proven a super form. there for a spider to a normal would give you 25% odds.

Unless there is a super spider I know not of? and my spiders have been playing tricks on me?

Edit:
Actually a Super would give 100% spiders. I dont see how you can get 50%? maybe a spider to a spider would drop those odds. But than I believe the super form of the spiders dont survive
