Is this snake catenifer or annectans? good question but there is only one way to know and that is to do a DNA work up. Because it is pet store snake and not wild collected you do not have any locality based info to use, and because it is a pet store snake you do not have any reliable breeder info to base an ID on. In the pet trade many animals that are heterozygous for a trait such as hypo melanistic or albino end up with lower sale value and get dumped on the pet store circuit. it was not uncommon for people to breed their applegate albino annectans animals to striped phase catenifer to get striped albino mutts. This has been going on for a while so there are alot of them out there. Also, keep in mind that the traits that distiguish catenifer from annectans overlap. In other words the saddle count range may be 21 to 26 for one subspecies and 25 to 30 for the other, (not actual numbers but given to make example).
The striped phase is most commonly seen in some populations of the nominant form catenifer but again there has been so much crossing. About as close as you will ever get realistically is that the snake is either catenifer or annectans and maybe/probably a mix.
Unless your pet store guy is really on top of things like the folks at Amazon reptiles you will always end up with issues like this.
And of course if I buy a snake that is misrepresented, breed it and sell the offspring calling them what I was told they were the myth gets perpetuated.
Its a nice looking snake but you should always consider it a mutt when and if you choose to breed it to something.
Sorry about the soap box but you did asked!
