“…We analyzed the genotype dataset for the Argus X-12 of 641 unrelated Mexican females from two Mestizo (n = 309) and seven Native American populations (n = 332) [7]. The Mestizo population sample included two main regions: Northwest (NW; n = 233) and Southeast (SE; n = 76).…”

“…Mestizo is a racial classification in the Mexican population that resulted from the admixture between the Native American and European individuals [164], and this racial classification makes up 90% of the Mexican population [176]. Despite the study [172] reported only on female samples of the Mexican populations, significant pairwise differentiation indicated a close relationship between Amerindian groups and Mestizos. Next, Baeta et al [164] also conducted X-STRs analysis on the Native American and the admixture group of Mestizo of Central America.…”

“…It is paramount to indicate here that while a great deal of studies on X-STRs population data have been reported, little emphasis has been given to the population data representing admixture populations. As a matter of fact, limited number of published articles [147,164,[171][172][173][174][175] reporting on the X-STRs population data of admixture populations are discovered, with none of them representing the Asian populations.…”

“…For example, Cortés-Trujillo et al [172] reported the forensic efficiency of the 12 X-STRs among women in two Mestizo admixture populations and seven Mexican Amerindian (indigenous people of America) groups. Mestizo is a racial classification in the Mexican population that resulted from the admixture between the Native American and European individuals [164], and this racial classification makes up 90% of the Mexican population [176].…”

The forensic DNA profiling technique has tremendously contributed to forensic human identification, an important aspect in forensic investigations. In instances whereby comparison samples are unavailable, utilization of short tandem repeats of X chromosome (X-STRs) may prove useful to resolve complex kinship investigations involving missing persons and mass disasters. Despite such evidential values, the use of X-STRs during investigations remains scarce in many Southeast Asian countries including Malaysia, requiring concerted efforts for establishing forensic statistical support for its diverse populations (especially the admixture populations), standardizing core loci and procedure, improving the knowledge among practitioners as well as developing suitable standard operating procedure for incorporating X-STRs analysis in the overall DNA profiling framework. Hence, this review paper aims to highlight the developments, applications and population data of X-STRs, as well as its challenges and future insights for forensic casework.

ObjectiveTo evaluate the genetic diversity, admixture, genetic relationships, and sex‐biased demographic processes in Mexican Mestizo (admixed) populations based on 10 X‐chromosome STRs (X‐STRs).MethodsWe analyzed the X‐STRs Decaplex system in 104 Mexican Native Americans to obtain the ancestral reference needed to complete the demographic analyses above mentioned. We included reported Iberian and Latin American (admixed) populations from Central and South America, as well as datasets from Mexican Mestizos based on Y‐linked STRs (Y‐STRs), autosomal STRs (A‐STRs), and mtDNA.ResultsHigher X‐linked Native American ancestry was observed among Latin American populations regarding that reported from A‐STRs and Y‐STRs. The interpopulation differentiation based on ancestry among Mexican Mestizos diminished according to the inheritance pattern: Y‐STRs (highest), A‐STRs, X‐STRs, and mtDNA (lowest). This finding is related to the peculiar admixture process that occurred during and after the Spanish Conquest of Mexico (and most of Latin America), involving a large number of Spanish men (Y‐chromosomes) with a lesser proportion of X‐chromosomes than autosomes; besides to the limited number of Spanish women (XX) arrived in the Americas in subsequent and shorter periods. Population expansion was detected in Mexican Mestizos from all the country, except those from the southeast region characterized by elevated indigenous ancestry, marginalization, and poorness.ConclusionsPopulation growth was detected in most Mexican Mestizos, besides more homogeneous and larger Native American ancestry based on X‐linked inheritance than that based on autosomal STRs and Y‐STRs.
