Candidate autosomal regions associated with reproductive isolation in the house mouse. Shared regions between the two transects exhibiting epistasis (this study) are shown in red. The QTL regions associated with hybrid sterility phenotypes (White et al. 2011) are represented as blue lines. Phenotype abbreviations, TW, relative testis weight; SD, sperm density; PC1, sperm head morphology; STA, seminiferous tubule area; DBT, distal bent tail; TAS, total abnormal sperm; H/T, headless/tailless correspond to those in White et al. (2011). Genes identified in Dean et al. (2008, 2011) are coloured in violet and those identified by Dorus et al. (2010) are coloured in green.
