Palmar creases in Spaniards.
In a sample of Spanish people (403 males and 513 females) the palmar creases have been studied according to the method of Bali & Chaube (1971). Bimanual differences are not statistically significant, but there is a sexual dimorphism. Comparing the incidence of the open M type defined by Tillner there are no statistical differences as compared with male German series, though they are seen in female series. It is observed that the frequency of the simian crease is in accordance with the variability of European populations.
