Quote:Conclusion
Family studies clearly demonstrate that tongue rolling is not a simple genetic character, and twin studies demonstrate that it is influenced by both genetics and the environment. Despite this, tongue rolling is probably the most commonly used classroom example of a simple genetic trait in humans. Sturtevant (1965) said he was "embarrassed to see it listed in some current works as an established Mendelian case." Tongue rolling is unsuitable for classroom use as an illustration of simple Mendelian genetics.
You must be one of those tongue rolling disabled freaks! :twisted:
