dominant question

[GenePirate]

ive been researching but have failed to find what im looking for. first i was intrested to know what spider x spider produces. then i found out they are dominant and only co-doms produce "supers" and i know recessive x recessive produce the same morph 100%. but what does dom x dom produce?

Dominant x dominant just produces dominant--the same phenotype--or normal depending on the gene distribution (like brown eyes x brown eyes = brown eyes in humans). Now, in the case of spiders, it's a little obscure. I think the lethal question may have been answered. I spoke with Kevin from NERD, the reported discoverer and largest producer of spider morphs, and they have not yet produced a spider that has two alleles for spider. In other words, they have not produced a spider that has only spider offspring. So, the evidence is leaning toward a homozygous spider lethality.
