Fig. 3From: Genome-wide introgression among distantly related Heliconius butterfly speciesPatterson’s D-statistic scans along the B/D and Yb mimicry loci scaffolds. For the tree topology above (a), clear introgression patterns (labeled with green bars) are observed along B/D between H. m. amaryllis and H. timareta and between H. besckei and H. m. nanna, using 5 kb adjacent windows (b)Back to article page
