Admixture and Heterozygosity in West Alaskan Populations
Summary Average heterozygosities for four communities (Savoonga and Gambell on St Lawrence Island, the King Island community now located in Nome, and Wales) are computed from blood allele frequencies. No significant relationship is found between this measure of heterozygosity and the amount of Europ...

Summary Average heterozygosities for four communities (Savoonga and Gambell on St Lawrence Island, the King Island community now located in Nome, and Wales) are computed from blood allele frequencies.
