Table S1. Summary statistics for microsatellites used for pedigree

advertisement
Table S1. Summary statistics for microsatellites used for pedigree creation and adoption detection. E1 = allelic dropout rate, E2 =
false allele rate, NA = number of alleles, HO = observed heterozygosity, HE = expected heterozygosity, Pex = probability of
exclusion for a single unknown parent, PID = probability of identity for unrelated individuals. For details on how each of these
numbers was calculated, consult the main manuscript.
