  1. 1The sites were referred to the location on the Z chromosome of the chicken genome sequences released in May, 2006 http://genome.ucsc.edu/cgi-bin/hgGateway;
  2. 2N indicated the number of tested chickens of each genotype;
  3. 3AFE = age at first egg, the values are least-square means ± standard errors (SE).
  4. a,bWithin a column, for each site, measurements with no common superscripts are significantly different in single marker analysis, but not significantly different after Bonferroni correction (0.0042 < P < 0.05); *indicate 0.0042 < P < 0.05.
