No evidence for linkage disequilibrium between Bf and GLO in African Negroids

Abstract
A sample of South African Negroids (n=791) was scored for each individual's Bf and GLO phenotype. (The genes for the Bf and GLO polymorphisms are included in a known cluster of linked genes on chromosome 6.) Following a χ2-test the respective two series of alleles were found to be distributed at random, i.e., there was no evidence for a linkage disequilibrium. This result is discussed in terms of the linkage relationships and map distances of the genetic markers involved.
