STR analysis.
Autosomal STR profiling is the standard method for paternity testing — it compares the pups' nuclear STR markers to Sadie and the alleged sire (Sam) to confirm/predict parentage. PCR is just a lab technique used to amplify DNA, mtDNA only traces the mother, and Y‑chromosome tests only give paternal lineage (less discriminatory than autosomal STR parentage testing).
