The study of finger dermatoglyphic patterns and the relation with blood groups in Fars ethnic women of Khorasan Razavi

Asymmetry as a morphological-anthropometric characteristic is developed for body axis formation. Dermatoglyphics studies the skin lines in palms, toes and fingertips accurately and systematically. The objective of this research is to investigate the relevance of the asymmetry lines of fingerprints and blood groups in a population of women living in Khorasan Razavi. For this purpose, after determining the blood groups, the fingerprints of the first phalange of the left and right hands of 53 healthy pregnant women (18 to 42 years old), were printed by ink and their dermatoglyphic patterns were compared in terms of quality and quantity and the patterns’ frequencies were determined in any blood group. In analyzing the data, we used SPSS 16 & MiniTaba 15 softwares. The findings suggest asymmetry in women with A blood group due to a significant difference in the ridge count of dermatoglyphic patterns between their right and left indexes (Mean difference: 2.72, Standard Deviation: 1.34) (p< 0.05). There was a significant difference between fingerprint patterns and the type of fingers in the right hand of women with B blood group and between fingerprint patterns and the type of fingers in the left hand of those with B and O blood groups (p< 0.05). There was a significant difference between fingerprint patterns and the type of fingers in the both hands of women with Rh+ blood group (p< 0.01). The present study reveals an association between the pattern of fingerprints and ABO blood groups.
