  1. *P < 0.05 (genome-wide)
  2. †P ≈ 0 (P-value too low to be determined by permutation testing)
  3. QTL were defined as suggestive if they were chromosome-wise significant at P < 0.05, while not experiment-wise significant at P < 0.05. The F ratio has degrees of freedom equal to the number of informative parents and the number of records (offspring) minus two times the number of informative parents [38]; the latter ranging from 3177 to 3737 depending on the number of marker-informative offspring. The proportion of phenotypic variance is the proportion of phenotypic variance explained by the QTL, after correction for selective genotyping.
