This is bogus. The ability to roll the tongue is learned. It is not genetically inherited, and we've known this from identical twin studies conducted in 1952. A later study confirmed the "learned" aspect.

"No. Your UU individual will always pass the dominant U allele to his progeny, and thus all of his progeny will have the ability to roll the tongue."
