Table S1 Autosomal microsatellite and sex-linked loci co-amplified in the multiplex stage. Multiple PCR products were then ‘singleplexed’ using a fluorescently-labelled forward primer at a locus-specific annealing temperature (Ta), prior to DNA size fragment analysis. ‘-‘ indicates loci that were not singleplexed for this study. References refer to the first known instance where these loci were used in orang-utans.

Statistics for microsatellite loci

The mean proportion of individuals typed was 0.9556 across 11 loci, of which the mean number of alleles per locus was 5.64. The mean expected heterozygosity over all loci was 0.6785, ranging from 0.4222 to 0.8572 per locus, and the mean observed heterozygosity was 0.7035, ranging from 0.3636 to 0.9111 per locus(Kalinowski et al., 2007). Further statistics are detailed in Table S2.

TableS2Summary statistics for the 11 microsatellite loci used in paternity analyses. ‘He’ and ‘Ho’ are the mean expected and observed heterozygosity values, respectively. ‘HWE-p’ indicates the p values for the significance of deviation from Hardy-Weinberg equilibrium, none of which were significant after Bonferroni correction.

TableS3Known, identifiable orang-utans that were sampled and genotyped for this study. ‘Mother' indicates that an individual's mother, and her genotype, are known. 'Status' denotes age and reproductive state; ‘-‘ is used when the individual was unborn. Young, dependent orang-utans are described as either infant (0-4 years) or juvenile (4-8 years). To avoid ambiguity, older males are described as 'unflanged' and older females as 'nulliparous'.* identifies orang-utans whose genotypes were used to test for linkage disequilibrium.‘X’ indicates that an individual was included as a candidate in parentage analyses.

TableS4Unknown, unidentifiable orang-utans that were sampled and genotyped for this study. 'Status' denotes age and reproductive state at the time of sample collection, either in the field season conducted from 2008-2009 or that in 2010-2011. ‘X’ indicates that an individual was included as a candidate in parentage analyses. The genotypes of all these orang-utans were used in the test for linkage disequilibrium.
