: This method is particularly useful in "kinship testing" where the alleged father cannot be sampled but his brothers, father, or other paternal male relatives are available. 2. Single Nucleotide Polymorphism (SNP) Typing
: Investigators upload a high-density SNP profile to public databases like GEDmatch or FamilyTreeDNA to find distant relatives (e.g., second or third cousins).
: SNPs can be analyzed from much smaller or more degraded fragments of DNA than STRs, making them ideal for identifying remains or aged biological evidence.
: Comparing antemortem and postmortem X-rays or dental records.

: Because the Y chromosome is transmitted directly from a father to all of his sons with minimal change, it can trace paternal lineage across multiple generations.
: SNP analysis can also provide biogeographic ancestry data, which helps investigators narrow down a "father's" identity by predicting physical characteristics (phenotyping) when no direct match exists in databases like CODIS . 3. Forensic Genetic Genealogy (FGG)
Traditional paternity testing relies on comparing at specific locations (loci) on nuclear DNA. However, "alternative methods" typically address scenarios where the alleged father is unavailable or the standard nuclear DNA is highly degraded. 1. Y-Chromosome (Y-STR) Analysis
