The aim of this paper was to explore hairiness of the middle phalanges on both hands fingers in the gym pupils. The total sample was 435 gim pupils in the town Niš, 281 girls and 154 boys aged 15-19 years. Most pupils (N=425) belonged to Serbian nationality. Hairiness and hairless on the middle fallanges of second, third, forth and fifth fingers was detected by inspection with magnifying glass. Results showed that the hairiness was more frequent on the fifth finger of right hand (p=0.05) and left hand (p=0.018) of the boys. Coefficient of the correlation had the highest values for the simultaneous hairiness on the middle falanges of third and forth fingers of the right (Ro=0.721) and left hand (0.653), then third and fifth falanges of right hand (Ro=0.455) and left hand (Ro=0.479) and the smallest, but yet significant values, were found for simultaneous hairiness of the second and fifth fingers of right (Ro=0.305) and left hand (Ro=0.339). The hairiness was present on all four phalangas in only 9 and 11 pupils of the right and left hand, respectively. The investigation of the hairiness on the middle phalangas of both hands in the region of Niš may be, in comparison with anthropological investigations of other regions, important in the investigation of the genetic cause of the hairiness on the middle phalanges. .
