Abstract

Properdin factor B is a genetically‐controlled polymorphism that can be demonstrated by agarose gel electrophoresis. The Bf gene frequencies were determined for 194 blacks from the south‐eastern United States. The frequencies for Bf‐F, Bf‐S, Bf‐F1, and Bf‐Sl are 0.626, 0.327, 0.034, and 0.013, respectively. The south‐eastern blacks have similar Bf frequencies to the South African blacks; however, both these groups are different from blacks from Boston. The frequency differences between south‐eastern blacks and Boston blacks may be due to racial admixture differences found in the two populations.
