Extended Data Fig. 3: Genome-wide marine–freshwater differentiation (FST) in the Atlantic, Eastern Pacific and Western Pacific Oceans.
From: On the causes of geographically heterogeneous parallel evolution in sticklebacks
(a–c) SNP-based FST of the individuals in the Atlantic (ATL), Eastern Pacific (EP) and Western Pacific (WP), respectively. Ecotype pairs follow the main analyses (Extended Data Table 2). (d) Window-based FST (win-size=100 kb) between EP freshwater samples (n = 13) and EP marine samples (n = 4). (e) Window-based FST between EP freshwater samples (n = 13) and all Pacific marine samples (n = 13). (d, e) are significantly correlated (r = 0.904, p < 0.0001). (f, g) SNP-based EP genetic parallelism (LD-clusters 2, 21, 29) for the same ecotype comparison as (d, e), respectively. Loci from LD-clusters involved in genetic parallelism are colour-coded for all panels (refer to main Fig. 2).
