Fig. 1From: Evolution of cis- and trans-regulatory divergence in the chicken genome between two contrasting breeds analyzed using three tissue types at one-day-oldCross design. Cornish-Game (CG) and White-Leghorns (WL) were used to generate purebreed and hybrid progenies. There were four crosses, Cross 1: CG × CG, cross 2: CG × WL, cross 3: WL × CG, and cross 4: WL × WL (the female parent is listed first)Back to article page
