Diversity indices for the MHC locus and microsatellites (averaged over 11 loci) in Arctic charr populations of Lake Peltojärvi and three presumably unstocked small Norwegian lakes from similar latitudes (Primmer et al. 1999). See electronic supplementary material, table S6 for more detailed information. no. A, number of observed alleles; Ar, allelic richness; Ho, observed heterozygosity.
