Spider Dominant Question

[BaLLPAddICT]

I don't have a very good understanding of genetics yet and I had a question. You know how breeders are selling spider morphs? Are they selling the het form or the homozygous form? Since they look the same you wouldn't be able to tell.. If they were selling them in their het. form would they refer to the homozygous mutants as supers?

So far as I know...all spiders could be (should be?) considered "hets"...meaning that if you breed them to a normal, you'll likely get a clutch that includes both normals and spiders. To the best of my knowledge, there has yet to be proven a "super" spider.


Certainly, no visible super spider has been revealed by anyone. But you'd expect that a true homozygous spider morph would throw 100% spiders when bred to a normal. I think a couple people have what MAY be homozygous animals, but no one is certain yet, that I'm aware of.

i see.. the only difference between dominants and co-dominants is that the het form of a dominant appears to look like its homozygous form, correct?

Dominant and Co-dominant both only require one copy of the gene to be present for the trait to show (unlike recessive, which requires 2 copies of the gene). The difference is that when is two copies of the dominant gene, it looks the same as if there was only one, but with co-dominant if there its two copies of the gene, it looks different than if there is only one.

I believe so.

Spiders dont have a super that only applies to codominat and incoplete dominate Homo and het look identical and essentially it really doesnt matter. all it would really do is allow you to produce a couple more spiders and i cant think of a test cross to prove it out
