Genetic genealogy integrates DNA testing with traditional paper-based documentary research. By analyzing autosomal DNA, Y-chromosomes, and mitochondrial DNA, researchers can establish biological relationships across generations. Reviewing clinical protocols in ISO accreditation standards ensures that laboratory methodologies deliver reliable marker comparisons for family history verification.
Autosomal testing measures inherited DNA across all autosomal chromosomes from both parents, useful for recent ancestry (4-6 generations). Y-DNA tests trace the direct paternal line, while mtDNA traces the direct maternal line.
Standard direct-to-consumer platforms allow users to download a text file containing SNP locations and genotype calls, which can be analyzed in secondary research databases.
