Table 1 Results of hybrid detection using structure at different assignment thresholds

From: Reintroductions and genetic introgression from domestic pigs have shaped the genetic population structure of Northwest European wild boar

Assign threshold >0.30 >0.25 >0.20 >0.15 >0.10  
Total hybrids 1 18 25 30 36 45  
Shared hybrids 2 3 5 6 6 7  
SNP60 only 3 6 4 3 3 2 Type II error
structure only 4 0 0 1 4 4 Type I error
  1. Comparisons were made to results from Goedbloed et al.[21], which identified nine hybrids from a total of 88 samples using analysis of introgressed allelic states with the SNP60 genotyping beadchip.
  2. 1 the total number of hybrids detected in this study by structure.
  3. 2 the number of hybrids from the SNP60 study that was correctly detected also by structure.
  4. 3 the number of hybrids from the SNP60 study that were not identified by structure (type II error).
  5. 4 the number of individuals that were incorrectly labelled as hybrids by structure (type I error).
