Individuals were derived from 14 source populations (S) and corresponding offspring cohorts (O) propagated at five different European breeding facilities. Genetic clusters present in source populations are highlighted in italic. Bold numbers refer to the number of samples in offspring cohorts belonging to the same genetic cluster(s) as the corresponding source population, regular numbers refer to the number of samples belonging to a genetic cluster not represented in the source population. Dashed lines delimit corresponding parental populations and offspring cohorts. N = number of analyzed samples, A = percentage of propagated individuals assigned to a genetic cluster represented in the corresponding source population.
