I don't think he said his woma were different line, but they were carring another gene.

Well, I don't know if he proved that gene could be isolated from the woma or not. But that's what I tought.

I would also like to know about more about the Pearl being lethal. I don't know how many breeders actually produced Pearl. I think a lot, just put their female woma to other project instead thinking it wasn't worth the try.

Woma are not as commun as spiders or some other gene. But I believe we should see more cross with it in the next few years. And may be more will try it with the Pearl. Just hope people let us know about it.
