Cohort composition for queries with matched and mismatched 1KGP populations. Rows are representative and colored by the population of the database (i.e., samples which can appear in the GenoSiS cohort); columns are representative of the query population. In cases in which the query and database sets were from the same superpopulation (diagonal), we separately label when the cohort samples matched the query samples’ sub- and superpopulation labels.
