Spider to normal suprise, comments please.

If there are homozygous spiders, it would still be considered a dominant trait, wouldn't it? Because the heterozygous phenotype would still be the same as the homozygous phenotype if this is an actual homozygous spider that the OP has.

Yes, this potential homozygous spider would be the first direct indication that spider might be dominant. It's been called dominant for years do to the lack of a visibly different super spider but that could also have been explained by spider being homozygous lethal which I think would qualify as a co-dominant mutation.

Would love to see these prove out regularly just to be sure this one isn't a fluke like maybe he is a paradox/chimera and his reproductive organs are one of the few parts that are homozygous spider. If he could be traced back to the breeder to see if he they even did any spider X spider breedings that year it would help to weigh if he is just a conventional homozygous spider or some more exotic explanation. Have to wonder why no other potential homozygous spiders became public in the decades before now.
