Statistics for the combined (1-PE) with one parent, by SNP set, and relatedness.

aRelatedness coefficient, i.e., the average proportion of genome shared between possible parents.bStatistics were calculated for each of the 74 breed groups (Table S2). The PE was calculated assuming the genotyping error rate was negligible, and only one parent was available (i.e., PE = 2(χ11)(χ22)).cThe 109 SNP set is a specific subset of the 163 SNP set (Table S1) and used in MALDI-TOF MS assays.dThe 57 and 52 SNP sets are specific multiplex combinations of the 109 SNP set (Table S1).
