| Summary: | Studies in a multitude of taxa have described a correlation between heterozygosity and fitness, and usually conclude that this is evidence for inbreeding depression. Here we have used multi-locus heterozygosity estimates from 15 microsatellite markers to show evidence of heterozygosity-fitness correlations (HFCs) in a long-distance migratory bird, the light-bellied Brent goose. We found significant, positive heterozygosity-heterozygosity correlations between random subsets of the markers we employ, and no evidence that a model containing all loci as individual predictors in a multiple regression explained significantly more variation than a model with multi-locus heterozygosity as a single predictor. Collectively these results lend support to the hypothesis that the HFCs we have observed are a function of inbreeding depression. However, we do find that fitness correlations are only detectable in years where population-level productivity is high enough for the reproductive asymmetry between high and low ... : Individual GenotypesDryad Data for MEC110746.xlsx ... |
