Over the years, I've seen plenty of misrepresented information in regards to this specific hybrid crossed animal. Many folks are very unclear as to what the genetic makeup of this animal started out as, and today, as with many other snakes that are bred, they can have all sorts of other genetic influences from other snakes that weren't part of the original animal's lineage.
The original Bubblegum Ratsnake was developed by Bill Love around 1990, then of Glades Herp Inc. He started with breeding the albino Black Ratsnake to a Yellow Ratsnake, he then later introduced the Everglades Ratsnake into the line for it's intense orange coloration. After all this was said and done, the snake that Bill coined "Bubblegum Rat" was a homozygous(visual) product of albino Black Rat, albino Yellow Rat, and albino Everglades Ratsnake cross.
Since those days, I've heard of all sorts of individual theories as to what constitutes their "bubblegums", and I'm sure from some of the conversations I've had with some, that there are now probably other ratsnakes involved in the mix as well,...not all, but certainly in some cases. Some I've talked to that have done some breeding didn't even know that the bubblegum Rat was actually an ALBINO form of these three snakes, they were calling the normal wild-type forms of this cross a "bubblegum rat". I've also heard people mention Gray Ratsnake being in this mix as well. No doubt there has to be a good number of animals in the hobby that are NOT products of this original cross of animals, yet are still being called bubblegums by individuals that are not aware of this,...but rest assured, a true "Bubblegum Ratsnake" is indeed a hybrid product of albino Black, albino Yellow, and albino Everglades ratsnakes combined.
Another part of what might contribute to their misunderstanding is there tendency to have many different looks,....they can range from very pale light pink animals with darker pink blotches, solid orange animals, orange and pink animals, to a busy complicated abstract patterned animal with vivid orange and pinks. The bottom line is these albino crosses can be extremely variable even though they share the exact same genetic lineage.
Below is a pic of what in my opinion are the very best looking examples of Bubblegum Ratsnake. This pic was from an animal rescue site up north that sold this and other animals for VERY affordable prices to good homes. Additionally, I have a good friend of mine that used to breed some very nice ones as well,...most of his were more of a slid type orange/pink coloration.
