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.
