The Spider is a dominant trait. What this means is that the heterozygous and homozygous type appear the same. Noone has proven to have a homozygous spider as of yet. Therefore the grand majority of the spiders in existence are believed to be heterozygous. Therfore, a spider bred to a normal would produce 50% spiders. All of the the spiders in the litter would be Het., meaning it only carries one spider allele. Hope this helps.
