While listed as dominant on many sites, Spider is probably not a dominant mutation. Instead, it may be co-dominant with a lethal super form, so that homozygous spiders never hatch.
It's not unusual for an egg or two to die during incubation, so it's unlikely it would be noticed.
Dominant Pin? Can you post links to this? Are there any known defects with them? Who usually has them available?
