Table 1 Allelic diversity of MHC class I and class II in five species of Centrocercus and Tympanuchus grouse, where n is the number of individuals genotyped, A is the number of alleles (private alleles in parentheses) and A/I is the mean (±s.d.) number of alleles per individual

  1. Abbreviation: MHC, major histocompatibility complex. Number of alleles was also estimated for T. cupido using a resampling approach (5000 replicates) based on 20 individuals to allow comparison with the other sampled species with a similar sample size. Note that A values for particular species do not sum to the total A because of interspecific allele sharing.
