Quizplus · Accepted Answer

The FBI uses 13 unique STR regions in forensic analysis, which are commonly referred to as the CODIS core loci. These regions are highly variable between individuals and allow for accurate identification and differentiation of DNA samples. The use of multiple STR regions helps to reduce the likelihood of a coincidental match between two individuals who share the same genetic profile at a single locus.
