Abstract.Bf phenotype distribution andBfallele frequencies in samples of the Norwegian population and the Lappish minority of Norway are presented.BfSin Norwegians was found to be 0.817, while it was 0.888 in Lapps. The difference is statistically significant. Possible explanations of this difference are discussed. It is noted thatBfallele frequencies of Norwegians are similar to those of Germans, while differing from frequencies found in US whites.
