Transferrin variability and founder effect in Iceland reindeer, Rangifer tarandus L.

Polyacrylamide gel electrophoresis was used to analyze transferrin variability in reindeer from Iceland and Norway. Blood samples from 74 reindeer from Iceland were compared with 199 samples collected from two herds of semi-domestic reindeer in Finnmark, Norway. Eight alleles were detected in both the Norwegian herds, namely TfA TFC1 TfE1 TfG1 TfH2 Tfl TfK and TfM. Only the three most frequent alleles, TfC1 TfE1 and TfH2 were detected in Iceland reindeer. The heterozygosity was high in both Norwegian herds, 0.695 and 0.762. but only 0.332 in the reindeer from Iceland. Founder effects are suggested to have been active in determining the genetic structure of the Iceland reindeer population.
