Abstract

This study investigated the genetic diversity of the Easter Island (Rapanui) population using data on 15 autosomal Short Tandem Repeats (STRs) typed with the commercial STR kits Identifiler® Plus and 23 Y-chromosome STRs typed using Y-filer (17 loci) and Y- PLEX™ 6 (6 loci). The analysis was conducted using genotype and haplotype data of 122 presumably unrelated individuals that included 48 males and 74 females. This study: (i) examined if Easter Island population had reduced genetic diversity in comparison with cosmopolitan populations such as Mainland Chilean, Polynesian, European, and African; (ii) compared genetic affinity of the Easter Island population with historically related cosmopolitan populations; and (iii) investigated the forensic utility of autosomal STRs and Y-STRs in the Easter Island population.
