  1. 1LTN, RTN and TTN mean the teat number on the left side, the teat number on the right side and the total teat number, respectively.
  2. 2Two imprinting effects were detected for RTN (0.12 ± 0.03) and TTN (0.16 ± 0.05) on SSC12, respectively.
  3. 3The QTL model with additive (A), additive and dominant (AD), or additive, dominant and imprinting QTL (ADI) effects.
  4. 4Chromosomal position.
  5. 5 **significant at the 5% genome-wise level; ***significant at the 1% genome-wise level.
  6. 695% confidence interval.
  7. 7Additive effect and standard error. A positive value means that the White-Duroc allele has a positive additive effect, and a negative value indicate that the Erhuanlian allele has a positive additive effect.
  8. 8Dominance effect and standard error.
  9. 9The percentage of phenotypic variance explained by the QTL.
  10. 10Threshold F-values for the suggestive level, significant at 5% and 1% levels for the three teat traits calculated in different models.
