There are three main types of DNA tests commonly used:
1. Y-DNA Testing
Y-DNA testing analyzes the Y-chromosome, passed down exclusively from father to son. This test is particularly useful for tracing paternal lineage and uncovering your direct male ancestors. It's excellent for researching family history along the male line.
2. Mitochondrial DNA Testing (mtDNA Testing)
Mitochondrial DNA testing focuses on mitochondrial DNA, inherited only from the mother. This test helps in tracing maternal lineage and discovering your direct female ancestors. It is particularly helpful in exploring deep ancestry and tracing family history through the mother's side.
3. Autosomal DNA Testing
Autosomal DNA testing examines autosomal chromosomes (non-sex chromosomes), inherited from both parents. This test provides a broader view of your ancestry, encompassing both maternal and paternal lines. It is the most commonly used type of DNA test for genealogy research and can reveal a wider range of relatives.
These three tests offer different perspectives on your genetic heritage and family history. The choice depends on your specific genealogical goals.
