The impact of haplogroup R1b-DF27 in Hispanic admixed populations from Latin America

Abstract

The study of Y-chromosome SNPs allows to link haplogroups to paternal biogeographical ancestry. The analysis of haplogroup R1b-M269 and its subhaplogroups in Latin American populations can help to assess the European paternal contribution. The objective of this work was to study the presence of R1b-DF27 in Latin American Mestizo populations. The obtained results reveal an average frequency of 29–35% with a north-south increasing pattern, seeming to agree with the influence of the Spanish commerce routes with America in the colonial era. Thus, the finding of DF27 in a forensic context could be due to individuals of both European and Latin American ancestry. In summary, the present work highlights the interest to further analyze R1b- DF27 in Latin America.
