Workflow of transcriptome meta-analysis (IMAGE) Hiroshima University Caption We obtained 46 pairs of pig and wild boar data and 59 pairs of chicken and red junglefowl data from public databases. By integrating and analyzing these data, we conducted comparative analyses of pig-wild boar and chicken-red junglefowl. Furthermore, we identified genes with common expression changes between domesticated animals (pigs and chickens) and their wild ancestors (wild boars and red junglefowl).
