We use the European House Mouse hybrid zone as a natural experiment to examine such forces. When SNP marker data is dense on the recombination map it cannot be treated as a series of independent loci but can, instead and more naturally, be analysed in terms of Fisher’s representation of the outcome of admixture and recombination: the ancestral source of blocks of DNA along the genome and the position of junctions (arising from recombination) where that source state changes. Cascades in the size of blocks allow ancestral polymorphism to be distinguished from introgression polymorphism. Frequency spectra of introgressed block sizes allow inference of the time since secondary contact. Geographic outlier analysis of blocks allow regions of the genome associated with the introgression of "antispeciation" genes across the species barrier to be identified. These insights increase our understanding not only of the mouse species barrier, but also how it can decay in its natural setting.
