- Your direct paternal lineage is the line that follows your father’s paternal ancestry. This line consists entirely of men. Y-DNA follows the direct paternal line. Your Y-chromosome DNA (Y-DNA) can trace your father, his father, his father’s father, and so forth. It offers a clear path from you to a known, or likely, direct paternal ancestor. Your Y-DNA may help you find genetic cousins along your direct paternal line.

About us About us. The Native American DNA Sequence is available for both males and females. For males, you can test for Native American ancestry in either your direct paternal (father's) or direct maternal (mother's) line of ancestors. For females, you can only test for native american ancestry in your direct matrilineal line.

- Roots for Real offers mtDNA and Y-DNA testing services. Roots for Real is now offering the DNA tracing service, as used in the BBC programme Motherland, to the general public. From a very easy to use home saliva test, Roots for Real will analyse your mtDNA (for maternal ancestry) or Y-DNA (for paternal ancestry) and match it to our database of samples from all over the world.

- DNA is the “gene” in genealogy. We all share some amount of DNA with our ancestors and relatives. Genetic genealogy is a tool to use in conjunction with traditional genealogy research that enables us to compare a small portion of our DNA to other people to determine if we’re related.

- DNA Analysis for Genealogy. When reproduction occurs, chromosomes from the mother and the father combine to form the chromosomes for the offspring. The DNA in these new chromosomes provide the genetic information for the individual, the so-called genome.

AncestryDNA - Frequently Asked Questions Unlike some other DNA tests, which only analyze the Y-chromosome (and can only be taken by a male to look at your direct paternal lineage) or mitochondrial DNA (can be taken by a male or female but only looks at your direct maternal lineage), AncestryDNA looks at a person’s entire genome at over 700,000 locations.

If two siblings with the same biological mother and father took an ancestry DNA test would their results be identical? Would they show identical percentages of ethnic and racial backgrounds? Now, if the two siblings were of the same sex then, yes, two brothers will (within probability factoring in mutations) inherit the same paternal DNA (Y DNA)—which is only one of the 23 you inherit, the other 22 will have more variations.

How to Use DNA Testing to Trace Your Family Tree Additionally, since women don't carry the Y-chromosome, their paternal male line can only be traced through the DNA of a father or brother. DNA tests can be used by genealogists to: Link specific individuals - e.g. test to see whether you and a person you think may be a cousin descend from a common ancestor.

AncestryDNA - Frequently Asked Questions Your DNA test results also provide information that’s more relevant and recent—targeting your family history a few hundred or even a thousand years ago, as compared to the Y-chromosome or mitochondrial DNA tests, which have a 10,000 to 50,000 year time focus.ou can link your Ancestry family tree to your DNA results on your personal status page. Just click on Settings and then scroll down to ‘Family Tree Linking’ to link your DNA results to a family tree. Currently, you can only link one tree to your DNA results.

Autosomal DNA Testing for Genealogy A recent breakthrough in DNA testing for genealogy is a new form of autosomal DNA testing. This type of test checks your autosomal chromosomes, the other 22 pairs beyond the sex-linked X and Y chromosomes.

- The Eve study examined mitochondrial DNA (mtDNA), which is passed only by mothers to their offspring. The researchers, Rebecca Cann, Mark Stoneking, and the late Allan Wilson, estimated that the ancestor of all surviving mt DNA types lived between 140,000 and 290,000 years ago.Illustration by Carlyn Iverson) [LARGER IMAGE]. DNA can be used to understand the evolution of modern humans, trace migrations of people, identify individuals, and determine the origins of domestic plants and animals. DNA analysis, as one scholar put it, is the greatest archaeological excavation of all time..

- DNA Relatives: How it works. DNA Relatives finds matches by comparing your DNA with other 23andMe members. When two people share identical segments of DNA, this indicates that they share a recent common ancestor. The length and number of these identical segments is used to predict the relationship between relatives.n general, for the same percent DNA shared, longer segments give a closer predicted relationship than a greater number of shorter segments. The estimate is based off a number of assumptions about population growth and characteristics of specific populations.

- Unlike the Y-chromosome or mitochondrial DNA test, AncestryDNA uses an autosomal DNA test that surveys a person’s entire genome at over 700,000 locations. It covers both the maternal and paternal sides of the family tree, so it covers all lineages.f you have taken one of the Y-chromosome and mitochondrial DNA tests, you will still have access to your results until September 30, 2014. You can access them here or on the AncestryDNA homepage. Please click here for more information.

Familial DNA Searches A familial DNA search is a search of DNA databases for relatives of a given DNA sample. Partial DNA matches from familial searches can provide likely identification of siblings, parents, children and other blood relatives. Current familial DNA searches only identify male relatives of male DNA samples.

Understanding genetic ancestry testing The father line is just one lineage in your family tree, and as you go further back in time it represents less and less of your total ancestry. For example, you have 64 great-great-great-great grandparents, and a Y-DNA test will only tell us about the ancestry of one of these 64 ancestors.
