Genetic variations that occur in humans are usually as a result of a plethora of factors which are of enormous valué from physical anthropological window especially in studying population variation and human diversity. This study was conducted amongst unrelated volunteer students of Delta State University, Nigeria who were all of Urhobo tribe (71 males) and (72) females aged between 18 years and over to determine their ability to roll or fold the tongues. The frequency of folders (120) and rollers (87) were more common than non-folders (23) and non-rollers (56).The incidence of tongue rolling was higher in females than in their male counterparts. These differences did not however show any statistical significance, p > 0.01. The frequency of R-F was observed to be highest in both males and females (38 and 43) respectively. 22 males and 17 females were observed to be capable of fold but unable to roll their tongue. None rollers and none folders were 9 males and 7 females respectively while rollers and none-folders were the least with frequencies of 2 males and 3 females respectively.
