Genetic genealogy is a method that combines traditional genealogy with DNA testing to help individuals trace their ancestry and family history. By analyzing specific markers in a person's DNA, researchers can identify genetic relationships and connections to distant relatives. This approach can reveal information about ethnic backgrounds and migration patterns, providing a deeper understanding of one's heritage. The process typically involves submitting a DNA sample, often through a cheek swab, to a testing company. The results can then be compared with those of other individuals in a database, such as AncestryDNA or 23andMe, to find potential relatives and build a family tree based on genetic links.
