  1. 1Pearson’s correlation coefficient of target gene against individual bodyweight of all three groups of birds (BW); *Sig at P < 0.05, **Sig at P < 0.01
  2. 2Relative direction of regulation: ↑ Broiler upregulated (broiler > cross > layer); ↓Broiler downregulated (broiler < cross < layer)
  3. a-cMeans (± SEM) within the same row for each parameter with different superscripts are significantly different (P < 0.05). Means values are counts per million (CPM) transcripts, to correct for varying sequence depth between individual samples
