Breeding a Yellow Rat to an Everglades Rat would create an intergrade, not a hybrid. Breeding a Yellow Rat or Everglades Rat to a Texas Rat would also create an intergrade. Hybrids are the crossing of two species, intergrades are the crossing of two subspecies. Yellow Rats and Everglades naturally interbreed as do Texas Rats and Black Rats, Black Rats and Yellow Rats, etc.

The babies would be vitually worthless as there's not much demand for hybrids and intergrades. This can be easily seen by no one wanting leucistic Black Rats due to speculation that they've been crossed with Texas Rats.

It's useful to determine if people would actually want the offspring you produce (if marketed honestly) before actually producing the snakes.
