Variation in number of presacral vertebrae (PSV) was examined in 462 vertebral columns in four populations drawn from tribal groups of Southern African Negroes. The total incidence of numerical variants (23 PSV and 25 PSV) was 19% in males and 12.1% in females. Males have a higher frequency of 25 PSV and females a higher frequency of 23 PSV, a sex difference reported by previous workers. Significant differences in the incidence of 25 PSV in males were present between S.A. Negroes, American Negroes and other racial groups. The total number of variants (23 PSV and 25 PSV) is significantly higher in S.A. Negro males (and higher but not significantly in females) than in the other groups; owing mainly to the findings in the Nguni-speaking sub-samples of the S.A. Negro. These findings support a previous suggestion based on combined-sex data that the frequency of numerical variations of PSV are characteristic of a population. It is suggested here that such frequencies are even more characteristic when males and females are considered separately.  相似文献

Digital and palmar dermatoglyphs in a random sample of normal Whites from Durban are described. The sample consisted of 200 males and 200 females. Features examined included frequency and distribution of finger patterns, digital and total ridge count, a-b score, and palmar topography. Data from this study are compared to similar data from South African Negroes, Indians, and Coloureds (mixed racial origin) and several outstanding racial characteristics are demonstrated in the dermatoglyphic profiles. It is suggested that the Indians' dermatoglyphic profile is dominant to those of Whites and Negroes.  相似文献

13 dermatoglyphic variables have been studied in eight population samples (five smaller isolated and three larger populations) to identify the possible differences between the larger and the smaller isolated populations. The data and neighbor joining trees for the dermatoglyphic variables show distinct differences between males and females. The isolated population of the Lutheran Mountains is clearly separated from the other populations. Combining the results of dermatoglyphic and 12 hemogenetic variables (only for six populations) the male and female trees are nearly identical. The three isolated populations are clearly separated, whereas the larger ones show smaller distances.  相似文献

The present report deals with the digital and palmar dermatoglyphics of the Elema peoples from the Gulf District of Papua New Guinea. The samples involved 91 males and 134 females from the areas of Iokea, Sepoe and Karama. The Elema dermatoglyphics, compared to those of other peoples in New Guinea, were found to have a high pattern intensity index and frequency of whorls, and the highest frequency of ulnar type C line, complete simian creases and patterns in the IV interdigital areas of the palms. On the other hand, their 11/7 ratio of the D line, the main line index, and the frequencies of patterns in the hypothenar, thenar/I and II interdigital areas were lower than most other groups on the island; they also have the lowest R/U ratio. All dermatoglyphic features considered, the frequencies in the Elema group were for the most part found to be near the extremes of the range of the dermatoglyphic frequency distributions in New Guinea populations. The dermatoglyphic distributions of New Guinea as a whole are discussed in terms of those of the other Australasian populations with comments on the dermatoglyphic comparisons between the Australasians and the other major human groups, Amerindians, Orientals, Asian Indians, Caucasians and Negroes.  相似文献

A comparison of the dermatoglyphic features of 60 Greek Cypriots from the coastal region of Yialousa and 60 from the isolated mountainous region of Troodos showed significant differences only in the frequencies of digital whorls and loops in the left hands of the males and in the frequencies of Thenar/I patterns in the palms of the females. All other comparisons produced nonsignificant differences. The overall dermatoglyphic similarities are in contrast to the previously described serological, hematological and historical differences indicating that the mountain and coastal people of Cyprus may be genetically distinct. Two possible explanations for the observed discrepancies between the blood group and dermatoglyphic findings were advanced: (1) The more involved inheritance of most dermatoglyphic features which renders them less vulnerable to the influence of isolation and genetic drift than the blood groups, and (2) the similarities in the frequencies of the dermatoglyphic features among the various ethnic groups of the eastern part of the Mediterranean.  相似文献

In the present paper data on finger and palm ridge counts of both hands are reported from representative samples of healthy Bulgarian males and females. Dermatoglyphic prints from both hands of 2431 Bulgarians (1161 males and 1270 females) have been taken in 116 settlements all over the country. The investigated males and females were healthy, not related persons of Bulgarian origin. The results of finger and palm ridge counts include basic statistics and correlations between ridge counts on separate fingers and the correlations between ridge counts in separate interdigital areas. The results, presented together with data on other dermatoglyphic features elaborated and published till now by the same authors for representative samples of Bulgarian males and females, can serve for the set up of a detailed data basis of the dermatoglyphic status of the Bulgarian population. At the same time they could serve as a norm for clinical and medico-biological investigations with theoretical and scientific applied purposes.  相似文献

It has been considered for many years that the cause of perinatal brachial plexus palsy (PBPP) is excessive lateral traction applied to the fetal head at delivery, in association with anterior shoulder dystocia, but this do not explain all cases of brachial plexus palsy. The incidence found in several family members could be suggestive for inheritance with variable expression. The aim of this study was to prove early found confirmations of genetic predisposition for PBPP In the previous studies, the quantitative dermatoglyphic analysis showed some differences in digito-palmar dermatoglyphs between patients with PBPP and healthy controls. Now this qualitative analysis will try to determine hereditary of those diseases. We analyzed digito-palmar dermatoglyphics from 140 subjects (70 males and 70 females) diagnosed with PBPP and 400 phenotypically healthy adults (200 males and 200 females) from Zagreb area as control group. The results of Chi-square test showed statistically significant differences for frequencies of patterns on fingers in females between the groups observed. Statistically significant differences were found on palms in III and IV interdigital areas in both males and females and in thenar and I interdigital area only in females. As it was found in previous researches on quantitative dermatoglyphic traits, more differences are found between females with PBPP and control group, than between males. The fact, that the main presumed cause of PBPP is obstetrical trauma, it could be associated with congenital variability in formation of brachial plexus.  相似文献

We have tested the hypothesis that the abnormal development of the central nervous system seen in endemic cretinism might be accompanied by concurrent abnormal dermatoglyphic patterns. We compared digital and palmar dermatoglyphics of normal individuals and endemic cretins inhabiting the Huon Peninsula of Papua New Guinea. The population sampled from the Irumu River Valley included 118 males and 114 females with 22 male cretins and 23 female cretins. The population sampled from the Wantoat River Valley included 72 males and 38 females with 12 male cretins. No pathognomonic patterns were found that could identify the endemic cretin subpopulation. However, the occurrence of a number of differences between controls and cretins suggests that subtle changes in dermatoglyphic patterns accompany the anomalous development of the CNS secondary to maternal iodine deficiency. We discuss the significance of these findings and compare the dermatoglyphic patterns of normal Irumu and Wantoat natives and 21 other populations of Papua New Guinea.  相似文献

In this study, we analysed inter-sex differences within two linguistic groups from the Sardinian linguistic area and intra-sex differences between the two groups by means of 41 quantitative digital dermatoglyphic variables: 20 digital dermatoglyphic traits (radial and ulnar ridge counts on each of the 10 fingers), 15 digital dermatoglyphic directional asymmetry variables, total finger ridge count, bilateral summed radial and ulnar finger ridge counts, an index of asymmetry between homologous fingers, and two indices of intra-individual diversity of finger ridge counts. The comparisons between males and females within the same linguistic groups and between the males of the two groups and the females of the two groups were carried out with the Mann-Whitney test at a prefixed level of alpha = 0.05, using the Bonferroni correction for multiple comparisons. The results indicate a strong similarity of the two linguistic groups in the inter-sex differences, whereas there are no significant differences between them for either males or females. The similar pattern of sexual dimorphism and the homogeneity of the males and females of the two groups suggest a common genetic matrix of these Sardinian-speaking groups.  相似文献

Digital and palmar dermatoglyphics of 184 male and 224 female normal American Negroes were evaluated for digital patterns, digital ridge counts, palmar patterns, palmar main line terminations, accessory triradii and palmar creases. All subjects were seven year olds examined and found free of chronic or other genetic diseases. The results were presented for the left and right hand for the most part comparable to those of the African and other American Negro groups reported earlier. The distributions of the various dermatoglyphic features among the Negroes taken as a group were compared to those of the other racial groups and their differences were discussed.  相似文献

This study was carried out to evaluate the effects of neoplastic diseases like carcinoma of the cervix and endometrial carcinoma, and was based on dermatoglyphic traits and their indices of intraindividual diversity (Div), fluctuating asymmetry (FIA) and directional asymmetry (DA). The results were compared with control groups of women and men, whose data have been detailed in our previous publications (Kobyliansky et al., 1999 a-d), and with analogous data of additional cancer groups available in the literature, like acute leukemia, bronchial cancer and breast cancer. The general aims of the study were as follows: (a) to obtain a dermatoglyphic characterization of discrete and quantitative traits and their Div, DA, FIA values in cancer patients, compared to healthy control groups, both female and male; (b) to test the hypothesis that in cancer patients there is an increased level of FIA as a result of an impaired developmental homeostasis; (c) to explore the possibility of using DT (dermatoglyphic traits) data of CW (women with cancer) to predict the probability of the appearance of cervical and endometrial carcinoma in apparently healthy females at a young age. The sample consisted of 94 Israeli-Jewish women of various groups, of which 54 had endometrial carcinoma and 40 had cervical carcinoma. The prints were collected in the Tel-Hashomer Hospital. The control group was a sample of 874 healthy subjects, half of them male and the other female, all from Jewish communities of European extractions (50%) as well as from Africa (50%). All controls were adults (over 18 years of age). Interpretation of prints was performed according to Cummins & Midlo (1961) and Penrose (1968) and included identification of patterns, ridge counts and the measurement of distances and angles in the palms, 79 DT for every individual were assessed. Significant differences were found for some of the studied traits between cancer patients and their healthy control groups. We encountered merely a low sexual dimorphism between the CW and the control males as compared to that between control males and females (with significant differences in 18% of the quantitative traits vs 64% in the control). The indices of diversity and asymmetry proved more suitable for discrimination, yielding the highest discrimination level between CW and control females. This finding suggested other data in the present study which points to a similarity between CW and control males.  相似文献

62 patients suffering from rheumatic heart disease were taken from Institute of Child Health, Niloufer Hospital, Hyderabad, for the present dermatoglyphic investigation. The finger, palm and toe prints were analysed to see if there was an association between rheumatic heart disease and any of the dermatoglyphic traits. The parameters which were significantly different from the controls are: (1) reduced frequency of arches on the finger tips in males and increased frequency of whorls in females; (2) increased frequency of patterns in the III interdigital area in males; (3) decreased d-t ridge count in females, and (4) higher incidence of multiple axial triradii in females.  相似文献

With the aim of determining sexual dimorphism in the component structures among the Chuvashian population of Russia, finger and palmar dermatoglyphics of 547 individuals (293 males, 254 females) were analyzed. The sex differences in two categories of dermatoglyphic traits (22 quantitative traits and 38 asymmetry and diversity traits) are reflected differently and contradictory with other ethnic groups. However, a common feature of the factor 1 "digital pattern size factor" (finger ridge counts from the first category of traits) indicate its degree of universality when compared with other populations, which suggests that the variability of finger ridge counts is determined by the same genes that control the pattern types. The factors "intra-individual finger diversity factor", and "bi-lateral asymmetry factor" extracted from the second category of dermatoglyphic traits are also similar in both sexes. However, these components are hardly described in the literature. The nature of variation of these components (from two categories of dermatoglyphic traits) appears with a good similarity between sexes, which suggests their common biological validity of the underlying component structures of the finger and palmar dermatoglyphic characters.  相似文献

Core(s) and triradii of dermatoglyphic whorl patterns were joined together to form triangles. Base angles of these triangles were measured (in degrees). The tangent angle at the lower edge of a ridge crossing the core-triradius line was also measured in degrees on each side of the whorl. Significant differences and similarities of these angles were investigated for unrelated Caucasian males and females by the use of Student's t- and Pearson's r-tests. Angular findings were related to the corresponding information provided by ridge counts. Similarities and differences between males and females are described.  相似文献

Some genetic traits in Solomon Island populations. IV. Mid-phalangeal hair   总被引:1,自引:0,他引:1  
Among 425 Lau and 467 Baegu of northern Malaita, there were no tribal differences in mid-phalangeal hair. The trait was present more often in males than in females, and after puberty than before it. Age differences were more marked for males than for females. Among 168 men 20 years of age and older in both tribes, the frequency of mid-phalangeal hair was 58.3%; among 189 women of similar age, 34.4%. These frequencies were at or just below those reported for Caucasian samples, just above that for Japanese, and considerably above those for Negroes and American Indians. Analysis of family data did not confirm the hypothesis that the absence of mid-phalangeal hair is recessive to its presence.  相似文献
