  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).
