(a) Different forms of the butterfly H. numata are associated with different genome arrangements in the region of the P supergene. Forms of H. numata are shown above the horizontal line, with their corresponding models beneath. Photos from Mathieu Joron. (b) Representation of the rearrangements on chromosome 2 of Zonotrichia albicollis associated with reproductive dimorphism. The inversions cover c. 105 Mb. Population genetics figures from Thomas et al. (2008). Figures for collinear region are for the marker SUPT3H. Pi values for the inverted region are for both loci considered together, and each separately. Photographs modified from Figure 1 of Horton et al. (2012).
