Serum protein (haptoglobin types; transferrin and group-specific component subtypes); haemoglobin and red cell enzymes (acid phosphatase, esterase D, glyoxalase I, 6-phosphogluconate dehydrogenase, adenylate kinase, and phosphoglucomutase (locus 1) (subtypes) were studied in the Sinhalese, Tamils, and Muslims of Sri Lanka. The allelic frequencies of all the polymorphic systems were similar in these populations without any significant differences. A close look at the present results and earlier investigations on 13 polymorphic loci controlled by 37 alleles did not reveal any genetic characteristics in the present-day Sinhalese population that are distinct from those in the Tamils of Sri Lanka. As such, genetic evidence linking the legendary origin of the Sinhalese population to East India (Prince Vijaya) is lacking. 相似文献

Background
The purpose of this study was to evaluate gender-wise diversity of digital dermatoglyphic traits in a sample of Sinhalese people in Sri Lanka.Findings
Four thousand and thirty-four digital prints of 434 Sinhalese individuals (217 males and 217 females) were examined for their digital dermatoglyphic pattern distribution. The mean age for the entire group was 23.66 years (standard deviation = 4.93 years). The loop pattern is observed more frequently (n = 2,592, 59.72%) compared to whorl (n = 1,542, 35.53%) and arch (n = 206, 4.75%) in the Sinhalese population. Females (n = 1,274, 58.71%) have a more ulnar loop pattern than males (n = 1,231, 56.73%). The plain whorl pattern is observed more frequently in males (n = 560, 25.81%) compared to females (n = 514, 23.69%).The double loop pattern is observed more frequently on the right and left thumb (digit 1) of both males and females. Pattern intensity index, Dankmeijer index and Furuhata index are higher in males.Conclusions
Ulnar loop is the most frequently occurring digital dermatoglyphic pattern among the Sinhalese. All pattern indices are higher in males. To some extent, dermatoglyphic patterns of Sinhalese are similar to North Indians and other Caucasoid populations. Further studies with larger sample sizes are recommended to confirm our findings. 相似文献
