Population Structure Analysis - Dermatoglyphic Latent Structure

Latent structure of quantitative dermatoglyphic traits has been analysed from the population in Middle Dalmatia: islands of Brač, Hvar and Korčula, peninsula of Pelješac and Makarska coastal region. We analysed 18 variables from fingers and palms, and principal component analysis was performed. In males we extracted 5 factors for all groups except island of Korčula (6 factors). In females we extracted 4 factors for the island of Korčula, 5 factors from the island of Brač and Pelješac peninsula and 6 factors for the island of Hvar and Makarska region. The total variance in males was from 70.41 % to 75.20 % while in females from 65.85 % to 79.27%. In all population groups on the first factor all fingers and on the second factor all palmar dermatoglyphs were extracted. In other factors there is evident variability of extraction, especially in females. The analysis of variables from extracted factors might give us information about similarities and differences between the groups concerning the latent structure, and also the differences and interindividual variability in females in comparison to the males. This study provides an insight into the effects of population structure and microevolution on quantitative variation.
