Compare your DNA with thousands of other samples to identify possible relations. Purchase a DNA test kit, submit a sample (a swab of cells from inside your mouth) then check the database for results. This test measures minor mutations over time.

Glossary – basic DNA terminology
- DNA – deoxyriboneucleic acid…The material inside the nucleus of cells that carries genetic information. Y-DNA determines whether a child will be male or female. It passes from father to son almost unaltered for long periods of time.
- Chromosome – bundles of tightly coiled DNA
- Gene – the physical unit of heredity passed from parent to offspring
- Genome/Genotype – all the genes or genetic information for an individual
- Locus (plural: loci) – a specific location on the genome
- Allelle – one of the different forms of a gene that can exist at a single locus
- Haplotype – linked loci that are inherited as a single unit
- Haplogroup – branches in the human genetic tree
- TMRCA – Time to the Most Recent Common Ancestor, expressed in generations
- Mutation – minor changes in the gene structure that occur between generations. The degree of mutation is used to estimate the number of generations.
