National DNA DAY

April 25 is National DNA Day, which commemorates the discovery of the structure of DNA by James Watson and Francis Crick in 1953 and the completion of the Human Genome Project in 2003.

Family Tree DNA is having a sale on Y-DNA testing today. A Y-DNA test can help you find genetic cousins through your direct paternal line. Although only men can be tested, women can ask a male relative to be tested.

Mitochondrial DNA testing can help you to learn more about your direct maternal line and your ancestral origins.

This map shows the migration patterns for mitochondrial DNA haplogroups. My mitochondrial DNA haplogroup is H2a.

Autosomal DNA testing can help you to find genetic cousins through any of your family lines. I matched with someone who turned out to be a descendant of my 5th-great-grandmother's sister.
