Sometimes, an objective of the genetic management of populations is to keep its original genetic background pure and remove any kind of undesired introgression. The present study tested different simulated scenarios trying to eliminate exogenous information by using two kinds of biallelic markers: unique (different alleles for natives and foreigners) and non-unique but with unbalanced frequencies in the natives. Selecting as parents those individuals with less exogenous influence (evaluated by the alleles of the markers) we reached a great depuration depending on the number of markers and the level of introgression. An increase of the inbreeding coefficient of the population is a side effect of the method.
