Abstract

Abstract: The continuous admixture events among Europeans, Native Americans, and Africans occurred differently throughout the Ecuadorian territory, creating a diversified genetic composition. Therefore, to evaluate how the genetic diversity is partitioned along the country for 15 STRs, 842 admixed-population samples were analyzed. We also evaluated the effect of applying an adjustment for population structure when estimating LRs using a national database. The results showed that to accurately assess forensic evidence, the use of a national database may be justified with the application of an appropriate adjustment for population structure.
