  1. Individual numbering corresponds to Goedbloed et al. [21]. The level of introgression is based on the number of introgressed domestic alleles per individual and expressed as being equivalent to the number of generations since hybridization according to simulations [21]. The type of hybrid (recent versus advanced generation) is distinguished based on the genomic distribution of introgressed alleles (clustered or spread out respectively) [21].
