DNA Tests Show Bias in Accuracy Across Different Ethnicities

A University of Oregon study highlights the limitations of forensic DNA analysis, particularly when dealing with DNA mixtures from groups with low genetic diversity. The research found that such mixtures are more prone to false positives, potentially implicating innocent individuals. This issue is exacerbated when more contributors are involved. The study underscores the importance of understanding the technique's limitations and the ethical challenges in genetic research, especially regarding informed consent.
