The ability to roll your tongue is a recessive genetic trait. A recessive trait is a genetic trait that may lie dormant in one sibling but can be active in the other, though the sibling with the dormant trait may have children who posses a particular trait like tongue rolling. http://www.mnsu.edu/emuseum/biology/evolution/genetics/mendelsvariation.html http://en.wikipedia.org/wiki/Punnett_square http://en.wikipedia.org/wiki/Dominance_relationship
