can low white spiders produce high white spiders when crossed to normal?

Agreed. They are like the pieds, you can't really make high white or low white, you get what you get. Maybe someday with more genetics worked out we'll be able to.

This is all I've heard and makes sense to me. Maybe with some very selective breeding you could influence it.

But yeah I think it is like pieds if I had to guess.
