1) Y-chromosome (Y-STR) analysis — Y-linked markers passed father to son.
2) Autosomal STR profiling — the short tandem repeat profiles used in the FBI/CODIS database.
3) Mitochondrial DNA (mtDNA) analysis — uses mitochondrial (non‑nuclear) DNA, useful for degraded samples.
4) PCR (polymerase chain reaction) — the amplification technique that duplicates tiny amounts of DNA for testing.
