Phenotypic variation in P. dardanus and the organisation of the H locus. (A) Female forms of P. dardanus (below the horizontal line) and examples of their model species in a number of African mimicry rings. The P. dardanus male pattern is shown boxed at the left along with male-like female forms. (B) Genomic organisation of the H locus showing the extent of exons (vertical blue bars) and introns (blue line) of the en and inv genes along the known sequence of the region. The bottom panels show the significance level for associations of SNP in the respective exons with three dominant morphs. The shading indicates the significance threshold for association. Note that significant association is found only in en (mostly exon 1). The figure is reproduced in an altered form from [25].
