Dermatoglyphic Studies among the Dumagat-Remontado Tribal Population of the Philippines

Abstract

Dermatoglyphics is the study of dermal ridges. Since dermatoglyphic characters are recognized as a unique individual trait and follow a multifactorial or polygenic pattern of inheritance, it is necessary to understand the variations leading to this pattern. The present paper, through appropriate descriptive approach, has revealed the variation in the pattern of inheritance in the TFRCs of the Dumagat-Remontados from Puray, Rodriguez, Rizal, Philippines. The study also reported a large discrepancy on the total fingerprint ridge count among the Dumagat-Remontados compared to established researches. Also, the increased heterozygosity due to genetic admixture led to the dominant occurrence of the loop pattern (ulnar) in the fingerprints of this group of indigenous people as compared to few established data stating that the frequency of whorl patterns dominates the universal population and other Asian racial groups. In this study, a special feature on the fingerprint patterns of the pure Dumagat-Remontados was reported. Aside from the high frequency of loops and whorls, a distinct club dent, concluded to be a unique feature found among this tribal population, was noted from at least one of the fingers of the majority of the pure sample.

“…The dominant of loop pattern in Javanese and whorl pattern in Madurese occurrence might have been due to the genetic admixture that happened in the current population through marriage. This result was supported by several previous studies in the DumagatRemontado tribal population of the Philippines to genetic admixture led to the dominant occurrence of the ulnar loop pattern in the fingerprints 15 and in the admixed population of Chinese the increase of whorl frequency 16 . This pattern can be influenced by many genes are involved 15 .…”

The study of fingerprints pattern have been accurate tool for personal identification and determination of paternity for quite some time.…”

Variations of finger dermatoglyphics among the Esan ethnic group of Edo State, Nigeria

“…This is so especially for researchers working in relation to genetics, medicine, and anthropology in a bid to explore genetically determined phenotypes, genotype and health diseases linkages. In this regards, Gutierez et al (2012) reported fingerprints to have been used for identification and authentication because of individual peculiarities and uniqueness and according to Temaj et al (2009) has served as an inexpensive and easily applied tool for estimating the genetic distances between populations. This is because fingerprint patterns are almost certainly influenced by the interaction of several genes and the ridge patterns are distinct and unique for every individual making it widely used in identification (Ismail et al 2009).…”

Relationship between Palmar Dermatoglyphic Pattern and Academic Performance of Students in a Ghanaian Secondary School

“…Each person has distinct and unique ridges on the fingers and palms that are genetically determined (Gutierez et al, 2012). Dermatoglyphic patterns are not influenced significantly after birth by environmental factors (Naffah, 1977).…”
