Please forgive my ignorance, but the internet has not been very helpful. I have seen some amazing pythons of gorgeous colors called "Jags". However, I can't seem to nail down whether they are always a cross between a Jungle Python and "whatever" or can be any cross of any two Morelia types. I have seen some advertised as "Jungle Coastal Jag" - a cross between both, or it's own type? I have also read that the gene which produces the beautiful colors can also be found to have caused some health issues later in the snakes life. Like I said.. heaps of info on the Net, but nothing very concrete. Hope these questions don't seem too silly.
