The number of significant differentially expressed genes in same breeds or stages and different breeds or stages. in bold: numbers of transcripts with difference abundance at the respective comparisons (GL63-GL91, PI63-PI93, GL63-PI63 and GL91-PI91) at p < 0.05. in parenthesis: number of transcripts with higher or lower abundance relative to the breed PI (↑ = PI higher or ↓ = PI lower)during development from 63 dpc to 91 dpc (↑ = increase, ↓ = decrease).
