Well the spider 66% het albino means there's a 66% possibility that it carries the one albino gene to make it het.

Assuming the spider 66% het albino proves out to actually be het albino, you could get spiders het albino, albinos, normals het albino and spider albinos.

However, if your spider doesn't prove out to be het for albino, then you'd get spiders het for albino and normals het for albinos.
