Population Studies in Northern Sweden: XIV. Variation of the A₁A₂B0 Blood Group Gene Frequencies

Frequencies of the A₁A₂B0 blood group genes were studied in a material of 5,632 conscripts and blood donors from the counties of Norrbotten and Västerbotten in northern Sweden. The individuals were distributed according to place of birth into 23 subpopulations. In northern Sweden different clines we...

Description
Summary:Frequencies of the A₁A₂B0 blood group genes were studied in a material of 5,632 conscripts and blood donors from the counties of Norrbotten and Västerbotten in northern Sweden. The individuals were distributed according to place of birth into 23 subpopulations. In northern Sweden different clines were found for the A₁, A₂ and 0 genes. The frequencies of the A₁ and A₂ genes were increasing in the northeastern respectively northern direction, and the frequency of the 0 gene was increasing in the southwestern direction. These geographical patterns could be explained in terms of Finnish and Lappish influence.
