Analysis of copy number variants of the duplicated alpha-, zeta-, and gamma-globin genes in eastern Polynesians revealed a high frequency of both triplicated-zeta-gene chromosomes and a specific alpha thalassemia deletion. This deletion and a novel restriction-enzyme-site polymorphism associated with a zeta zeta zeta chromosome are found only in Melanesians and Polynesians. Analysis of alpha-globin restriction-enzyme haplotypes indicated further similarities to Melanesians but suggested an additional non-Melanesian genetic component in eastern Polynesia. Several globin gene alleles showed evidence of marked frequency fluctuations due to genetic drift.
