A short mapping with why:
- A correct father is identified — DNA paternity testing using autosomal STR profiling (DNA fingerprinting).
Explanation: comparing the child’s and putative father’s autosomal STR markers shows whether the father contributed the expected alleles.
- A suspect is identified using a small sample of evidence — PCR-based STR profiling (PCR amplification of STRs).
Explanation: PCR lets forensic labs amplify tiny or degraded amounts of DNA so STR profiles can be generated and matched to a suspect or database.
- A missing person is correctly identified — mitochondrial DNA (mtDNA) analysis or kinship STR testing (and Y‑STR for male-line cases).
Explanation: mtDNA is abundant and survives well in hair/bone/old/degraded samples and can be matched to maternal relatives; Y‑STRs help when tracing a male-line relative; autosomal STR kinship testing is used when close relatives are available.
