Abstract

Human aconitase (ACONS) polymorphism was studied in three samples from northeastern Brazil. Two of the samples were collected in the State of Bahia and one in the State of Sergipe. The main characteristic of the samples was given by different degrees of Black admixture. The results showed that the more negroid the samples the higher the frequencies of the alleles ACONS4, ACONS2 and ACONS6. These findings fit well with the known ACONS gene frequencies in present-day Nigerians and with the past history of Yoruba slaves in Bahia.

摘要

对来自巴西东北部的三个样本进行了人类乌头酸酶（ACONS）多态性研究。其中两个样本采集于巴伊亚州，一个样本采集于塞尔希培州。这些样本的主要特征是具有不同程度的黑人血统混合。结果表明，样本中黑人血统比例越高，ACONS4、ACONS2和ACONS6等位基因的频率就越高。这些发现与当今尼日利亚人已知的ACONS基因频率以及巴伊亚州约鲁巴奴隶的历史情况非常吻合。
