Then you want the World of Ball Pythons link above. Also http://www.reptileforums.co.uk/forum...ts-morphs.html
There are a variety of other threads about genetic defects in ball pythons, too.
As far as I know, nobody has turned up any cases of sex linkage or linkage in ball pythons.
There are a couple of books available --
Kevin McCurley, The complete ball python
John Berry, Designer morphs
I have not gotten my hands on either one because they are rather expensive.
Good luck.
