Исследования показывают, что умение сворачивать язык в трубочку не является примером менделеевского наследования признаков: http://udel.edu/~mcdonald/mythtongueroll.html Причем это признал сам автор открытия, Alfred Sturtevant: "In 1952 Matlock ("Identical twins discordant in tongue-rolling." J. Hered., 43:24.) showed such a high frequency of discordance to exist between members of pairs of identical twins that even if an inherited component is an actuality (which is not certain), there is sufficient nongenetic influence to make the character practically useless as a genetic marker. But I am still embarrassed to see it listed in some current works as an established Mendelian case." A History of Genetics (Harper & Row, 1965)
