  • For a marker with a positive estimated additive effect, the effect on weight is caused by the allele with its origin in the line associated with the sign of the effect, i.e., an allele with its origin in high-line is associated with an increase in body weight and an allele with its origin in low-line is associated with a decrease in body weight. In cases where a weight-increasing allele has its origin in the low-line or a weight-decreasing allele has its origin in the high-line the sign of the estimated additive effect will be negative.

  • b QTL name as in Jacobsson et al. (2005).

  • c Base pair position according to Chicken genome assembly (galGal3) of May 2006.

  • d SNP name as in NCBI dbSNP where imputed markers are labeled with i after the marker name.

  • e Difference in allele-frequency between the HWS and LWS founder lines.

  • f Additive effect ± SE calculated in a model including all loci in the table.

  • g Significance of the estimated additive genetic effect in a model including all loci in the table.
