Modelling the Consequences of Domestication-Introgression in Wild Populations Using Genetic Markers Under Varying Degrees of Selection.

ABSTRACT: Introgression of domesticated genomes influences the evolutionary trajectory of wild populations. Genetic markers are used to quantify admixture in wild populations subjected to introgression from non-native conspecifics. However, markers can be under direct and indirect selection which may influence admixture estimates and quantification of fitness consequences thereafter. We expanded the Atlantic salmon eco-genetic model IBSEM to compute individual fish phenotype and domestication admixture using markers under variable strengths of selection. Following 50 years of 5%-25% domesticated conspecifics on the spawning grounds, the recipient wild population showed an increase in adult size at age and a decline in adult abundance, both of which scaled with the degree of intrusion.
