Intergenerational Trend of Some Dermatoglyphic Traits in Vaidyas of West Bengal, India

Sažetak
In order to investigate the intergenerational change of dermatoglyphics, fingerprints
of 400 individuals were collected from an endogamous caste Vaidyas of Barasat, West
Bengal. Results were compared with the data of an earlier sample of Banerjee collected
in 35 years before on the same community of the same area. As it is generally known that
dermatoglyphics is selectively neutral, thus if no other evolutionary forces play a role,
we cannot expect any change of dermatoglyphic characters after several years. In the
present study, non-significant change in the frequency of pattern and more or less same
PII have been observed in both sexes. But significant quantitative differences were found
between the two samples. These differences may not be due to the change of intra-uterine
environment, rather due to the inter-observer error of these two studies and the small
sample size of the earlier study. Because though same methods were used in both studies,
inter-observer variation is much possible in ridge counting than pattern type determination.
