Population studies in northern Sweden. X. The MN blood groups.
Frequencies of the MN blood groups were studied in a material of 3,312 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. The frequency of the M gene was significantly higher in Norrbotten county than in Västerbotten county. The overall picture of geographical variation was, however, not explainable in terms of Lappish and Finnish influence. In Västerbotten county a significant departure from the Hardy-Weinberg equilibrium (excess of heterozygotes) was found. The inbreeding coefficient FST was found to be high (5.3 . 10(-3)) and significant (p less than 0.001) in Västerbotten county, but low (1.2 . 10(-3) and statistically not significance in Norrbotten county.
