Y-DNA Testing

Information stored in the Y-chromosome passes virtually unchanged from father-to-son for centuries. Analysis of this genetic information, found in living people, can help you determine whether or not you share a common ancestor with another person alive today. Computer algorithms predict approximately how long ago the common ancestor lived. These results have many genealogical applications.

MTDNA Testing

Autosomal DNA Testing

DNA Testing Companies

Some major commercial DNA testing companies are listed below in alphabetical order. Please visit their websites to learn more about their services:

Public DNA Databases

The Sorenson Molecular Genealogy Foundation is a non-profit organization dedicated to building the world's foremost collection of DNA and corresponding genealogical information. SMGF is making some information available on their web site. Finding matching DNA results and pedigrees in the Sorenson Database can help you make new family connections throughout the world and across generations.The Foundation is a world leader in DNA research with direct application to genealogy. Their work complements other studies that focus on the "deep ancestry" of humankind.

Result Interpretation Assistance

Organizations, such as The Genetic Genealogy Consultant, provide services to help you interpret your DNA results and get the most out of what they can tell you about your roots.

DNA Projects

Thousands of DNA Projects, usually focused on a particular surname, location, or ethnicity, are active around the world. To determine if a DNA project is underway for your ancestor's surname, start with World Families Network.

Other DNA projects can be found on the Internet by using a search engine, such as Google, with the words "Genealogy DNA". Contact each organization for additional information.

Examples of individual projects include:

What is DNA?

DNA research is based on the 46 chromosomes that every human being has (with few exceptions). The gender determining chromosomes are X from the mother and either X or Y from the father.  If X from the father, the child is female and if Y from the father the child is male.  The Y-chromosome can be traced from father to son to son and so on.  The mother has a mtDNA which is something of an energy source for the cells.  All children of one mother have the same mtDNA as do all children of that mother's daughters, though not of her sons since mtDNA can't be passed by men.  Since the mutation of chromosomes is very slow the study of the Y-chromosome or the mtDNA trail forms the basis of the DNA genealogy.
