Author Contributions
RHC, KS and CHF conceived and designed the research; DdV collected data; AS and KS analysed SNP data to generate relatedness and internal relatedness information; KS analysed the data, with input from LK and CHF; KS and RHC wrote the manuscript, and all authors contributed to reviewing and editing.
Figure 1. Distribution of (a) internal relatedness of koalas used in analyses, and (b) pairwise relatedness from the matrix used to estimate additive genetic variance. Pairwise relatedness was estimated using Queller and Goodnight estimate (Queller and Goodnight 1989), where, for instance, full-sibs and parent-offspring pairs would have a value of 0.5, and half-sibs would have a value of 0.25.
