Non-native species experience novel selection pressures in introduced environments\u00a0and may interbreed with native lineages.\u00a0Species introductions therefore provide opportunities to investigate repeated patterns of adaptation and introgression across replicated contact zones.\u00a0Here, we investigate genetic parallelism between multiple introduced populations of the invasive marine mussel,\u00a0Mytilus galloprovincialis, in the absence (South Africa and California) and presence of hybridisation with a native congener (Mytilus planulatus\u00a0in Batemans Bay and Sydney Harbour, Australia). Repeatability\u00a0in post-introduction differentiation from native-range populations varied between genetically distinct Atlantic and Mediterranean lineages, with Atlantic-derived introductions displaying high differentiation (maxFST>0.4) and parallelism at outlier loci. Identification of long non-coding RNA transcripts (lncRNA)\u00a0additionally allowed us to clarify that\u00a0parallel responses are largely limited to protein-coding loci, with lncRNAs likely evolving under evolutionary constraints.\u00a0Comparisons of independent hybrid zones revealed\u00a0differential introgression most strongly in Batemans Bay, with an excess of\u00a0M. galloprovincialis\u00a0ancestry and resistance to introgression at loci differentiating parental lineages (M. planulatus\u00a0and Atlantic\u00a0M. galloprovincialis).\u00a0Additionally,\u00a0contigs putatively introgressed with divergent alleles from a closely related species,\u00a0Mytilus edulis, showed stronger introgression asymmetries compared to genome-wide trends and also diverged in parallel in both Atlantic-derived introductions. These results suggest that divergent demographic histories experienced by introduced lineages, including pre-introduction introgression, influences contemporary admixture dynamics. Our findings build on previous investigations reporting contributions of\u00a0historical introgression to intrinsic\u00a0reproductive architectures shared between\u00a0marine lineages and illustrate that interspecific introgression history can shape\u00a0differentiation\u00a0between colonising populations and their\u00a0hybridisation\u00a0with native congeners.
