“…Another study on sub-Saharan Africans has also shown that the values of TFRC found among the Zimbabweans were higher in men than in women (Igbigbi and Msamati, 2002). These results were also comparable to those obtained in the Zulus of South Africa (Grace and Ally, 1973). The Southern Nigerians have a significantly higher TFRC than those previously reported for the Zulu.…”

Background: The human dermatoglyphic traits present variations within and between populations and could be used for estimating the genetic distances between populations. Aim: This study aims to characterize the dermatoglyphic traits in the Tunisian population and to analyze eventual differences between men and women and between individuals according to their geographical distribution. Subjects and Methods: Several dermatoglyphic traits have been determined and analysed for 343 Tunisians belonging to six groups distributed on different Tunisian regions. For statistical analysis, the percent frequency, chi square test and t-test were used. The cluster analysis was applied on D 2 Mahalanobis distance matrix. Results: The chisquare test revealed high significant differences between the sexes for the frequencies of arches in the case of the fifth finger and for the frequencies of loops in the case of the fourth left finger and the first left finger. The difference of the distribution of whorl type between men and women was statistically significant for the fourth left finger. While no significant differences were found between sexes in finger ridge counts. Conclusion: The intra-Tunisian population analysis shows that Tunisians living in the North and the expanded East Centre of Tunisia are genetically very close, while Tunisians from the extreme East Center and the South of Tunisia are relatively less close to them. This conclusion agrees with that deduced from recent molecular marker analyses and shows that the multivariate analysis of a high number of quantitative digito-palmar dermatoglyphic traits represents a powerful and shrewd tool in intra-population analyses.

“…The considerably low TRC obtained by Grace and Ally [1973] among the Zulus is, however, not seen in our studies among the Southern Nigerian Negro. The TRC in Zulu males and females were 129.9 ± 45.7 and 119.6 ± 49.6, respectively, while the Nige rian figures were 143.3 ± 43.3 and 130.5 ± 51.5.…”

“…This finding is in agreement with those of Grace and Ally [1973] in their studies among the Zulus of South Africa. Even though Grace and Ally attributed this surprising finding to sampling error, our studies which confirms theirs may indicate that sex difference in atd angles is a feature of 'Negro-dermatoglyphics.…”

“…This higher frequency of arches in the females seems to be sufficient to explain the higher value of TRC in the males. This is true for the South African coloureds [Grace and Ally, 1972b], the South African Negro [Grace and Ally, 1973] and the South Af rican Whites [Grace, 1975]. This similarity in the trend of TRC in vastly dissimilar ra cial groups tend to indicate that the arch pattern frequency and TRC in normal sub jects are predominantly influenced by the sex chromosomes [Penrose, 1968].…”

Dermatoglyphic features of 200 male and 200 female normal Southern Nigerian negroes have been analysed. The frequency distributions of fingerprint patterns, digital and total ridge counts TRC, a–b scores and atd angles are given. In common with other races, the Southern Nigerian population showed the tendency for females to have more arches than males. Like the Zulus of Southern Africa, Southern Nigerian Negroes showed a significant sex difference in the atd angle but the Southern Nigerians have a significantly higher TRC than those previously reported for the Zulu. This study, contrary to previous studies, suggests that low TRC is not a negroid dermatoglyphic trait.

“…Parents of all investigated subjects are healthy and of the same ethnic group. Three samples are used as outgroups: Africans [28], [29], Caucasians [3], and Gin Vietnamese [30]. 121 samples from 56 ethnic groups in China as shown in Table 1 contain a total of 68,846 individuals with 35,950 males and 32,896 females (excluding Indian Tibetans (T.B.-1)) [16].…”

Dermatoglyphics from All Chinese Ethnic Groups Reveal Geographic Patterning

et al. 2010

Completion of a survey of dermatoglyphic variables for all ethnic groups in an ethnically diverse country like China is a huge research project, and an achievement that anthropological and dermatoglyphic scholars in the country could once only dream of. However, through the endeavors of scientists in China over the last 30 years, the dream has become reality. This paper reports the results of a comprehensive analysis of dermatoglyphics from all ethnic groups in China. Using cluster analysis and principal component analysis of dermatoglyphics, it has been found that Chinese populations can be generally divided into a southern group and a northern group. Furthermore, there has been considerable debate about the origins of many Chinese populations and about proper assignment of these peoples to larger ethnic groups. In this paper, we suggest that dermatoglyphic data can inform these debates by helping to classify a Chinese population as a northern or southern group, using selected reference populations and quantitative methods. This study is the first to assemble and investigate dermatoglyphics from all 56 Chinese ethnic groups. It is fortunate that data on population dermatoglyphics, a field of physical anthropology, have now been collected for all 56 Chinese ethnic groups, because intermarriage between individuals from different Chinese ethnic groups occurs more frequently in recent times, making population dermatoglyphic research an ever more challenging field of inquiry.
