I'm not entirely sure I understand the question(s). :shrugs:
As far as autosomal goes, I believe that the most, if not all, morphs are thought to ultimately be a result of autosomal mutations/genes/etc.
Autosomal simply refers to any chromosome other than a sex chromosome. I know the book states that sex-linkage has been suggested with some of the pinkish hues in anerys and the differences between male and female hypo lavs.
Maybe I am missing it, but I'm not seeing the mention of non-random assortment. You are referring to recombination, yes?
