Digital and palmar dermatoglyphics and the population structure of the Upper Bologna Apennine

Abstract

Analysis of digital and palmar dermatoglyphics in an Italian mountain population was carried out. Dermatoglyphic variability was particularly investigated in samples from four different valleys. Microgeographical differences in qualitative and quantitative traits among valleys were found. The relationship between degree of endogamy and dermatoglyphic differences is discussed. The biological repercussion of isolation in the history of this Apennine population is also pointed out by means of comparisons with a nearby plains population characterized by low inbreeding.
