Data from: Gene flow from domesticated escapes alters the life history of wild Atlantic salmon
Interbreeding between domesticated and wild animals occurs in several species. This gene flow has long been anticipated to induce genetic changes in life-history traits of wild populations, thereby influencing population dynamics and viability. Here, we show that individuals with high levels of intr...
