Behavioural isolation may lead to complete speciation when partial
postzygotic isolation acts in the presence of divergent specific mate
recognition systems. These conditions exist where Mus musculus musculus
and M. m. domesticus come into contact and hybridize. We studied two mate
recognition signal systems, based on urinary and salivary proteins, across
a Central European portion of the mouse hybrid zone. Introgression of the
genomic regions responsible for these signals: the major urinary proteins
(MUPs) and androgen binding proteins (ABPs) respectively, was compared to
introgression at loci assumed to be nearly neutral and those under
selection against hybridization. The preference of individuals taken from
across the zone regarding these signals was measured in Y mazes, and we
develop a model for the analysis of the transition of such traits under
reinforcement selection. 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.
