Fluctuating asymmetry of paired morphological structures is regarded as a measure of developmental stability. To test whether
poorly canalized individuals are highly sensitive to postnatal environmental influence, we accepted the exogenous disease
low-back pain as an example of such sensitivity. Asymmetry of the palmar a-b ridge count was examined in 217 males suffering
from low-back pain against 300 healthy controls. Low-back pain patients showed significantly higher values of asymmetry indices
indicating lower developmental stability. The results suggest that dermatoglyphic asymmetry can mark phenotypes weakly adapted
to postnatal stress. 相似文献

Quantitative Fluctuating (FA) and Directional asymmetry (DA) of dermatoglyphics on digito-palmar complex were analyzed in a group of 111 patients (males: 61, females: 50) with schizophrenia (SZ), and compared to an ethnically matched phenotypically healthy control (males: 60, females: 60) through MANOVA, ANOVA and canonical Discriminant analyses. With few exceptions, asymmetries are higher among patients, and this is more prominent in FA than DA. Statistically significant differences were observed between patient and control groups, especially in males. In both sexes, FA of combined dermatoglyphic traits (e.g. total finger ridge count, total palmar pattern ridge count) are found to be a strong discriminator between the two groups with a correct classification of over 83% probability. 相似文献

Fluctuating asymmetry (FA) was calculated for nine paired morphometric characters in a randombred population of house mice in order to assess the effects of age, sex, and phenotypical extremeness. FA did not significantly vary between sexes for any of the characters, and age proved to be significant only for innominate length. Additionally, FA values in high extreme individuals and low extreme individuals were compared to those for intermediate individuals to discover whether extreme individuals showed increased fluctuating asymmetry (decreased developmental stability) due to increased levels of homozygosity. Differences in fluctuating asymmetry magnitudes were found between the groups, although the extreme individuals did not consistently show increased fluctuating asymmetry and FA differences also showed no significant association with the level of heritability of each character. Potential reasons for these findings are discussed. 相似文献

Fluctuating asymmetry (FA) is defined as random deviations from bilateral symmetry of the body. Thus, its magnitude is often used to evaluate developmental homeostasis. In this study we evaluate the following hypotheses: 1) FA of dermatoglyphic traits has a significant genetic component; 2) prenatal maternal environment (PME) has a significant effect on the FA of dermatoglyphic traits in developmentally healthy individuals; and 3) genetic or environmental factors affect FA on organismal or systemic levels. Therefore, their effect is better seen in composite scores of FA rather than in FA indices for single traits. We analyzed 15 dermatoglyphic traits from 140 pairs of monozygous twins, 120 pairs of dizygous twins, and 106 pairs of mothers and daughters. All individuals were developmentally healthy. The influence of genetic and environmental factors on FA was evaluated by analysis of variance and regression analysis. For a majority of the traits in our study, FA showed significant but weak heritabilities, with values falling within the 0.20-0.35 range. None of the traits taken separately demonstrated the effect of PME on FA to be significantly greater than zero. The composite score of FA tended to have greater heritability values than individual traits. One of them, obtained in principal components analysis, showed a significant PME effect, supporting the hypothesis that FA is a systemic property. 相似文献

A study of fluctuating dermatoglyphic asymmetry in the sibs and parents of cleft lip propositi. 总被引:3,自引:0,他引:3 下载免费PDF全文
Fluctuating asymmetry was studied in cleft lip propositi and their normal sibs and parents. The traits examined were a-b ridge counts and fingerprint patterns. Propositi with a family history of this congenital malformation and their normal sibs and parents were significantly different from the controls for this type of asymmetry. Propositi without a family history and their normal sibs and parents were similar to the controls. These results support the hypothesis that familial and sporadic cases of congenital cleft lip are different entities and give evidence for a genetic mechanism in the parents and sibs of the familial cases that may account for this congenital disorder and, concomitantly, increased fluctuating asymmetry. 相似文献

Quantitative dermatoglyphic characters of fingers and palms of 61 male patients with fra-X-syndrome and 20 female heterozygote carriers were analysed and compared with the data from 84 male and 90 female normal individuals. Univariate and multivariate analysis of the data led to the following conclusions: 1. The fra-X-syndrome patients show higher ridge count and higher MLI value (increased transversality of the main lines), and lower a-b ridge counts than the controls. In addition to this, differences are observed also for the diversity and asymmetry measures. 2. Discriminant analysis as applied to the sexes separately, showed that 75% of males can be correctly classified in their group. However, the percent of correctly classified females is lower than the males; it is 70% (fra-X female) ad 64.4% (control female). 3. D2-matrix and the comparison of TFR C values support the hypothesis of X-chromosomal doses effect on the dermatoglyphics. 相似文献

Palmar dermatoglyphic prints were taken of 261 dyslexics (173 males and 88 females) and compared against those of 707 controls (372 males and 335 females). Dyslexics of both sexes were found to exhibit greater complexity in terms of ridge count and pattern location than controls, particularly on the left hand. Specifically, both male and female dyslexics exhibited higher left a-b counts, wider atd angles on both palms, and higher frequencies of pattern in left interdigital area IV. Additionally, male dyslexics also had higher right a-b counts and greater frequency of pattern in the left hypothenar area. Dyslexics of both sexes were also found to have more distally located axial triradii, and investigation of bilateral asymmetry found dyslexics to exhibit more directional asymmetry than controls in the variable of a-b count, with the left value for both groups being greater than the right. It was concluded that the study evidenced strong support for the hypothesis that some causative factor relating to the development of dyslexia is operating during the time period in which dermatoglyphic features are formed. The relevance of these findings in terms of the Geschwind hypothesis and the possible importance of prenatal testosterone are discussed. 相似文献

The present study is carried out to evaluate the effect of chromosomal morbidity (82% are 47XXY and in the remaining cases
there is the extra X and/or Y) in the males with Klinefelter’s syndrome, based on dermatoglyphic traits and indices of diversity
and asymmetry. The main objectives of the present study is to find dermatoglyphic traits and fluctuating asymmetry indices
which could be “marker traits” and could indicate the degree of developmental instability of the organism. The sample of males
with Klinefelter’s syndrome (N=171) was collected in the Institute of Human Genetics of Sheba Medical Center, Ramat-Gan, Israel,
by Professor Bat-Miriam Katznelson during 20 years, between 1968–1988. All patients were confirmed by chromosomal examination.
The finger and palm prints were collected with the aid of pads manufactured by Lamedco Inc., Knoxville, Tennessee, U.S.A.
Interpretation of the prints was according to Cummins and Midlo (1961) and Penrose (1968) and included identification of patterns,
ridge counts and the measurements of distances sum of and angles in the palms. 79 dermatoglyphic variables for every patient:
28 continuous traits, 9 discrete traits, 11 indices of intra-individual diversity, 15 indices of directional asymmetry and
16 indices of fluctuating asymmetry were estimated. The problem of asymmetry, fluctuating and directional and of intraindividual
diversity of quantitative dermatoglyphic traits is reviewed here as well as illustrated by data obtained on a sample of healthy
control group of Jews from Israel. In this first part of our paper we will discuss the data on individual dermatoglyphic traits
on digits and palms. The second part will be dedicated to multivariate analysis in order to compare between Klinefelter’s
syndrome and control healthy individuals based on quantitative dermatoglyphic traits and indices of diversity and asymmetry. 相似文献
