Scaleless Texas Ratsnakes ( Pantherophis obsoletus lindheimeri ) have been in the hobby for a couple of decades, it was proven to be a simple recessive gene by Dr Betchel in 1990. He obtained in 1985 a pair of Scaleless Texas Ratsnake hatchlings from the Bronx Zoo, the female died of gastrointestinal disease, but the male thrived. When sexually mature he was bred to a wild type female resulting in four wild type hatchlings, three females and one male. The three F1 females were bred back to the original male, producing 9 scaleless snakes and 14 scaled from 3 clutches containing a total of 23 eggs.
