Increased efficiency in geographic ancestry assignment and human identification by combining lineage profiles: The case of the iranians

Authors


ABSTRACT

Objectives

This research is a first empirical attempt to quantify the increase of the among-groups variance and the probative value of a DNA evidence when combining profiles based on markers with uniparental inheritance.

Methods

Yfiler and HVS-I panels of loci were analyzed in 130 healthy unrelated males from six Iranian native groups.

Results

A separate analysis of DNA profiles at the two lineage markers failed to detect a population substructure, whereas maximum levels of genetic diversity (HD = 1) and discrimination capacity (DC = 1) were obtained by combining the two profiles.

Conclusions

When combined, the forensic efficiency of routinely used panels of lineage markers can be largely sufficient to resolve cases of geographic ancestry and human identification even in genetically homogeneous populations. Am. J. Hum. Biol. 26:413-416, 2014. © 2014 Wiley Periodicals, Inc.
