Table 2 Means for eggshell-quality traits among genotypes and the SNP contribution to phenotypic variance (CPV) of the single-nucleotide polymorphism

From: The sodium channel gene family is specifically expressed in hen uterus and associated with eggshell quality traits

  1. 1EW = Egg Weight; ESP = Eggshell Percentage; ESS = Eggshell Strength.
  2. EST = Eggshell Thickness after correction; % indicates these traits relative to Egg Weight.
  3. 2Different superscript (a, b, c) in the same row means phenotypes are significantly different between different genotypes (P < 0.05).
  4. 3CPV = SNP contribution to phenotypic variance (%).
