Table S5. Half sib, full sib and parent-offspring pairs detected by KINSHIP and ML-Relate analyses. In
addition to the related pairs identified by KINSHIP, the table includes ML-Relate results, in which the
most likely relationship is at least twice as likely as the pair being unrelated (LR>2). KINSHIP results
are represented by the significance level in tests of the suggested kinship against a null hypothesis of
“being unrelated” (***, p<0.001; **, 0.001<p<0.01; *, 0.01<p<0.05). RQG, relatedness coefficient; HS,
half sib; FS, full sib; PO, parent-offspring; ML-kin, most likely relationship according to ML-Relate; LR,
likelihood ratio: likelihood of the most likely relationship divided by the likelihood of “unrelated”.
The number of related pairs detected by KINSHIP is higher than the number of false positives
expected at a significance level of 0.05 (among contemporaneous breeders: 8 half-sib, 5 full-sib and 6
parent-offspring pairs; 5 false positives expected for each type of kinship in 93 comparisons; among
all breeders: 17 half-sib, 12 full-sib and 17 parent-offspring pairs; 13 false positives expected for each
type of kinship in 253 comparisons; among the full sample: 72 half-sib, 80 full-sib and 55 parentoffspring pairs; 63 false positives expected for each type of kinship in 1275 comparisons.)
