研究短串联重复vWⅢ基因应扩增片段长度多态性及其法医学意义。应用STR-PCR分型法对200名中国辽宁汉族无关个体的短串联重复VWFⅢ的多态性进行调查。共检出8个等位基因,频率分布在0.003~0.333,基因长度范围为154~182bP,个人识别能力为0.921,非父排除率为0.581。群体调查证实该基因座符合Hardy-Weinberg平衡,家系调查结果表明其遗传符合孟德尔方式。该基因座可作为人类群体遗传学的一个有价值的多态性标记,可用于法医学个人识别及亲子鉴定。 相似文献

During an extensive multipopulation study with Y-short tandem repeat (STR) loci, amplified using the AmpFlSTR Yfiler PCR amplification kit, amplification of a 71 bp fragment was observed in 2.32% of the male samples analyzed (N = 3141). By direct sequencing of this fragment, it was determined that the primer binding sequences were identical to those of the DYS456 locus. A T to G single-nucleotide polymorphism (SNP) enabled amplification of the 71 bp fragment. The SNP is located within an X-Y homologous region at Xq21.31 and was observed with the highest frequency within the African American and Sub-Saharan African populations in our study. Presence of SNP on the X chromosome did not interfere with the reliability of typing the DYS456 locus and the other Y-STR loci typeable using the AmpFlSTR Yfiler PCR amplification kit. Full profiles in a mixture of male:female at 1:4000 were obtained using the current configuration of the AmpFlSTR Yfiler kit even in the presence of female DNA containing the G variant. 相似文献

POPULATIONS: The population studied was the Tujia population, living in the Hunan Province, China. Their ancestors had lived in the region for at least three generations. As a Chinese minority group, the Tujia ethnic group, with a population of 8,028,133 (year of 2000), is mainly distributed in the Wuling mountain area in the three provinces of Hunan, Hubei, and Sichuan. The Tujia population have their own language, which belongs to the Tibetan-Myanmese Language Group of the Chinese-Tibetan Language Family, but the large majority have come to speak the Han and Miao languages, now that the Tujias have been largely assimilated. 相似文献

Research has devoted substantial attention to patterns of offending during the transition to early adulthood. While changes in offending rates are extensively researched, considerably less attention is devoted to shifts in the type of offending displayed during the transition to adulthood. Changes in the type of offending behavior suggest a pattern of “displacement” or shifts between various types of crime, rather than desistance from deviant behavior. In this paper, I integrate methods previously developed in stratification research and use longitudinal data from the National Survey of Youth that span the transition to adulthood to examine the extent to which desistance and displacement of deviant behavior are defining attributes of offending during the transition to early adulthood. The findings indicate that while desistance is clearly present, altering patterns of offending, or within-person displacement, rather than termination of illicit activity is most evident in the data.

云南汉族人群11个Y-STR基因座遗传多态性调查及法医学应用 总被引:9,自引:0,他引:9
目的调查11个Y-STR基因座及其单倍型在云南汉族人群中的遗传多态性分布,探讨其法医学应用价值,为法医学应用提供基础数据。方法应用Powerplex!Y系统对云南汉族201名无关男性个体进行11个Y-STR基因座的复合扩增,用ABI310型基因分析仪对扩增产物进行检测,统计其群体遗传学参数。结果Powerplex!Y系统前10个Y-STR基因座分别检出3、5、6、8、5、4、5、8、4、7个等位基因,DYS385a/b基因座检出56种单倍型;GD值最低为0.4273(DYS438),最高为0.9747(DYS385a/b);观察到11个Y-STR基因座共同构成的单倍型175种,其中有154种单倍型只出现1次,16种出现2次,5种出现3次,累计GD值为0.9984。结论11个Y-STR基因座具有较强的个体识别能力,可应用于云南地区汉族人群的个体识别与亲权鉴定。 相似文献

What transpires in a dispute, even a violent dispute, is affected by the tendency for adversaries to engage in “limited offending.” We focus on one restraint: the tendency of men to limit their aggression in their disputes with women. Analyses are based on an incident-level survey about interpersonal disputes administered to 503 men who are incarcerated and 220 men who had never been incarcerated. Using multinomial and logistic regression models, we examined the extent to which an adversary's gender predicted dispute-related behaviors. The evidence suggests that the chivalry norm has pervasive effects on the behavior of men during their disputes with women. Men are more likely to engage in remedial actions (e.g., apologies) when their adversary is a woman, as opposed to another man. In addition, men are less likely to make violent threats and engage in physical attacks when their adversary is a woman, even after they have themselves been physically attacked. When men are violent, they are less likely to injure a woman than a man. However, the chivalry norm does not inhibit verbal aggression in these disputes: men are just as likely to engage in verbal attacks and nonviolent threats when the adversary is a woman. 相似文献
