    We studied two mate-recognition signal systems, major urinary proteins (MUPs) and androgen binding proteins (ABPs), across a Central European portion of the mouse hybrid zone. Introgression of the genomic regions responsible for these signals was compared to introgression at loci assumed to be nearly neutral and those under selection against hybridization. The strongest assortative preferences were found in males for urine and females for ABP. Clinal analyses confirm nearly neutral introgression of an Abp locus and two loci closely linked to the Abp gene cluster, whereas two markers flanking the Mup gene region reveal unexpected introgression. Geographic change in the preference traits matches our reinforcement selection model significantly better than standard cline models. Our study confirms that behavioural barriers are important components of reproductive isolation between the house mouse subspecies.
