Clusters resulting from the hierarchical clustering of DE genes using Pearson correlation coefficient. Seven clusters were obtained from the expression profiles of DE genes in at least one comparison. Chickens were incubated and reared in standard conditions (Controls, C), thermally manipulated during embryogenesis and reared in standard conditions (TM), incubated in standard conditions and exposed to heat challenge at d 34 (CHC) or thermally manipulated during embryogenesis and exposed to heat challenge at d 34 (TMHC). Clusters were generated with MeV software
