Finger ridge count in Basque populations: univariate and multivariate comparison with other Spanish populations

SummaryWe have analysed finger ridge counts in the indigenous Spanish Basque population (841 males and 911 females). Bimanual and sexual variation have proved to be statistically significant. The results in the Basque population were compared with those of other Spanish populations. In the univariate comparison statistically significant differences appear. The means found in the Basque population are the lowest. Our population is situated on the lower part of the variation range of the European populations for whom data are available. In principal component analysis the first two components explain more than 90% of the total variability. The first component is interpreted as a size component, which is usual. The factor scores of the individual samples have proved to be very useful in showing which populations are nearest to the Basque one.
