  bibo_abstract:
  - The Mytilus complex of marine mussel species forms a mosaic of hybrid zones, found
    across temperate regions of the globe. This allows us to study ‘replicated’ instances
    of secondary contact between closely related species. Previous work on this complex
    has shown that local introgression is both widespread and highly heterogeneous,
    and has identified SNPs that are outliers of differentiation between lineages.
    Here, we developed an ancestry‐informative panel of such SNPs. We then compared
    their frequencies in newly sampled populations, including samples from within
    the hybrid zones, and parental populations at different distances from the contact.
    Results show that close to the hybrid zones, some outlier loci are near to fixation
    for the heterospecific allele, suggesting enhanced local introgression, or the
    local sweep of a shared ancestral allele. Conversely, genomic cline analyses,
    treating local parental populations as the reference, reveal a globally high concordance
    among loci, albeit with a few signals of asymmetric introgression. Enhanced local
    introgression at specific loci is consistent with the early transfer of adaptive
    variants after contact, possibly including asymmetric bi‐stable variants (Dobzhansky‐Muller
    incompatibilities), or haplotypes loaded with fewer deleterious mutations. Having
    escaped one barrier, however, these variants can be trapped or delayed at the
    next barrier, confining the introgression locally. These results shed light on
    the decay of species barriers during phases of contact.@eng
