Whole-genome sequencing of crosses between Spanish and Swedish Littorina saxatilis
Laboratory F1 crosses were generated between a Swedish Crab ecotype female (sampled at 58.833472 N, 11.138778 E) and a Spanish Crab ecotype male individual (sampled at 42.077239 N, 8.896519 W). The F0 parents and their F1 offspring were whole-genome sequenced (Illumina). In addition, field-collected Spanish and Swedish individuals from the same populations were sequenced.
