Genetic Evidence for Hybrid Trait Speciation in Heliconius Butterflies (original) (raw)
Figure 1
Relative likelihood of association between H. heurippa and H. m. melpomene versus H. c. cordula for (A) genes unlinked to color pattern and (B) across the HmB red color pattern locus.
Likelihood values are plotted for each variable position, where positive likelihood values indicate a SNP position at which H. heurippa and H. m. melpomene are more similar, and negative values a position at which H. heurippa shows a stronger association with H. c. cordula. Fixed sites are indicated by dotted lines showing a likelihood value of 244 for a complete association of H. heurippa with H. m. melpomene and −244 for that with H. c. cordula. Colors represent different coding regions. The majority of unlinked SNPs (634) show shared polymorphism among the three species (240> ΔLnL >−240). At unlinked loci, H. heurippa and H. c. cordula shared fixed polymorphism at only 8 SNPs whereas H. heurippa and H. m. melpomene did not share any fixed polymorphism. For the HmB locus, sequenced BAC clones are indicated above the gene annotation [41].
