Frequencies of atypical serum cholinesterase among Caucasians and Negroes from southern Brazil.
Frequencies of the CHE1*A allele were estimated on the basis of a sample of 999 Caucasians (1.5%) and 1,015 Negroids (0.84%) from Curitiba, Brazil. The frequency found in the Negroid subsample allows an estimate of 50 +/- 15% of Caucasoid admixture and an average gene flow in the white-black direction of the order of 5.6% per generation.
