Fig. 4From: Strong selection pressures maintain divergence on genomic islands in Atlantic cod (Gadus morhua L.) populationsPatterns of coancestry (\(f\)) on chromosomes 1 (a), 2 (b), 7 (c) and 12 (d) for the CC, NEAC, CC × NEAC and \( f_{{{\text{CC}}\;{\&}\;NEAC}} \) populations. Genomic islands with significantly higher or lower coancestry are shown in greyBack to article page
