Check out www.ralphdavisreptiles.com/collection/pythons/ball/ .. use the drop down box at the top right to see each morph and read about the genetics.
Also, check out www.newenglandreptile.com/ball_gallery.html
As for male or female, in terms of genetics there is no difference. In terms of limited funds or breeding projects, the immediate advantage that I can think of is that a single male morph can be bred to multiple females (normals, hets or homos) whereas once your female of a morph is knocked up, that's it for her breeding abilities for that year.
Good luck
