Human aconitase polymorphism in three samples from northeastern Brazil.
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.
