Summary
The allele frequency of a Taq 1 γ-globin gene restriction fragment length polymorphism (RFLP) is reported in ten population groups. In four African populations the 3.0 kb RFLP is common (50/132 {ie90-1} chromosomes), whereas it is completely absent in six European/Asian populations (0/277 {ie90-2} chromosomes). This Taq 1 RFLP is thus a specific African population marker.
