ASCLD Webinar Series: DNA Mixtures Technical Overview

ASCLD Webinar Series: DNA Mixtures Technical Overview


Complex DNA mixtures from more than two individuals and/or profiles amplified with low-level quantities of DNA, can be challenging for the analyst to interpret. The FBI’s Scientific Working Group on DNA Analysis Methods (SWGDAM) crafted a new version of the autosomal DNA STR interpretation guidelines that most of the DNA laboratories in the country look to for guidance in analyzing DNA profiles. Mr. Sutton presented information on the changes to the interpretation guidelines including the background and scope of the changes. Mr. Heidebrecht and Ms. Conway answered questions and provided additional comments. Mr. Buckleton spoke about the PCAST report and the impact the report is having on the Forensic DNA community.
