Fig. 3. Optix-bound loci with strong signatures of selection drive genomic differentiation between Radiate and Postman metapopulations.
The dome/wash color-patterning locus exemplifies a strong signal of selection (A) on an Optix binding site that displays elevated population differentiation (B) and population divergence (C). Loci with strong signals of selection (selected loci) and the “pigment-associated” subset show increasingly significant population differentiation (D) and divergence (E) between Radiate and Postman metapopulations relative to the genome-wide distributions.
