Fig. 3: Projections of IC and DC CREs show similar enrichment of functional chromatin marks in the chicken genome.

a, Classification of elements with or without conserved activity (±). Signal enrichment at chicken genomic regions to which mouse CREs were projected. b, Fractions of mouse CRE orthologs (LiftOver: minMatch = 0.1; IPP: DC, IC, NC) overlapping an ATAC-seq peak in chicken HH22/24 hearts. c, Fraction of mouse CRE orthologs (LiftOver: minMatch = 0.1; IPP: DC, IC, NC) overlapping an H3K27ac ChIP–seq peak in opossum adult livers.
