“…Chi-squared analysis of variance showed there is a significant difference (P<0.05) between those who could roll and fold their tongue and those who cannot. The findings above are similar to the study of Alfred (Sturtevant, 1940;Bulliyya, 2003;Odokuma et al, 2008;Maishnam, 2012). When males were compared with females, a higher percentage (71.0%) were folders as compared to (66.1%) female folders.…”

This study investigated Variation in cerumen type, tongue rolling and tongue folding abilities of the Esan people of Southern Nigeria. This cross-sectional survey investigated 400 volunteered adult subjects (176 males and 224 females) between the ages of 18 and 60 whose parents and grandparents were of Esan ethnicity. The tongue and ear wax type were observed and examined physically thus classifying subjects into rollers/none-rollers, folders/none-folders and dry or wet cerumen type. Results indicates that tongue rollers (72.9%) were more than non-rollers (27.3%), in the same vein, tongue folders (68.3%) were also more than non-folders (31.7%) in the studied population. A larger percentage of the population also had wet ear wax (65%) while (35%) had dry ear wax. The chisquared analysis of variance showed that there is a significant difference (P<0.05) between those who can roll their tongue and those who cannot, those that could fold their tongue and those who cannot as well as between those with wet ear wax and dry ear wax. This study therefore provides data on the distribution of tongue rollers, tongue folders as well as variability in cerumen type. This data can be of importance to the anthropologist and forensic investigators.Keywords: Variation, Genetics, Inheritance, tongue rolling, tongue folding, cerumen type

“…Odokuma et al, also observed a higher incidence of rollers and folder among the Urhobo people of Nigeria (Odokuma et al, 2008). Maishnam reported higher percentage of rollers and folders in six different type tribes of Manipur, India (Maishnam, 2012).…”

“…We are aware of only one study carried out in Southsouth Nigeria by Odokuma et al (2008) which focused on the incidence of these traits with respect to sex. The aim of the study was to determine the frequency distribution of tongue rollers and tongue folders among the Yoruba tribe of Southwestern Nigeria with a view to determining if there was any association between the ability to roll and fold the tongue.…”

IGBENEGHU, C.; OLUKANNI, F.; OLISEKODIAKA, J. & ADESINA, A. Association between tongue rolling and tongue folding in Osogbo, Southwestern Nigeria. Int. J. Morphol., 34(3):866-869, 2016. SUMMARY:This study was carried out among 144 individuals (≥18 years) from the Yoruba tribe of Southwestern Nigeria in order to determine the association between tongue rolling and folding. Participants were examined for the ability to roll and/or fold their tongues. The incidence of tongue rollers and folders were 59.7 % and 79.2 % respectively. Tongue rolling was higher in females than male but the difference was not significant (X 2 = 1.039, df = 1, p= 0.308). Tongue folding was significantly higher in females than males (X 2 = 4.211, df= 1, p= 0.04). Of the 144 participants, 76 (52.8 %) were tongue rollers and folders, 10 (6.9 %) were rollers and non-folders, 38 (26.4 %) were non-rollers and folders and 20 (13.9 %) were non-rollers and non-folders. These classes did not vary significantly with sex (X 2 = 5.895, df= 3, p= 0.117) but there was a significant association between the ability to roll the tongue and the ability to fold the tongue (X 2 = 10.97, df= 1, p <0.001). This study shows that tongue rollers are associated with tongue folders.

“…On the other hand, Martin (25) reported that there was no proof for a genetic base of tongue rolling. In a more recent study, it was emphasized that tongue rolling is likely to be product of autosomal genes (26). Our result indicated that there was no significant relationship between tongue rolling ability and other investigated parameters (Table 3).…”
