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.
