  abstract = {{U}nraveling the evolutionary mechanisms and consequences of hybridization is a major concern in biology. {M}any studies have documented the interplay between recombination and selection in modulating the genomic landscape of introgression, but few have considered how associations with phenotype may affect this landscape. {H}ere, we use the {E}uropean seabass ({D}icentrarchus labrax), a key species in marine aquaculture that undergoes natural hybridization, to determine how selection on phenotype modulates the introgression landscape between {A}tlantic and {M}editerranean lineages. {W}e use a high-density single nucleotide polymorphism array to assess individual local ancestry along the genome and improve the mapping of muscle fat content, a polygenic trait that is divergent between lineages. {T}aking into account variation in recombination rates, we reveal a purging of {A}tlantic ancestry in the admixed {M}editerranean populations. {W}hile {A}tlantic individuals had higher muscle fat content, we observed that genomic regions associated with this trait in {M}editerranean populations displayed reduced introgression of {A}tlantic ancestry. {T}hese results emphasize how selection against maladapted alleles shapes the genomic landscape of introgression.},
