The site, Family Tree DNA, was established to help individuals connect with their past. This company has been in business since April of 2000. Since that time, their data base has grown constantly. As of October 20, 2010, the database has grown to 312,596 different DNA sample results that can be searched for a match.  A quick check as of July 23, 2011, this database has grown to 341,154 records!

Genetic Genealogy:

When the total number of records is broken down, there are 6,117 different surnames in the data base along with 193,585 records of Y-DNA and 119,011 of mt-DNA. This is the largest assembly of DNA records and results anywhere in the world.

Family Tree is considered the world’s leader in genetic genealogy that works with a scientific advisory board and is affiliated with the University of Arizona research labs.

Family Finder:

The newest test being offered by this genetic testing lab is the Family Finder. This test can take either the Y-DNA or mtDNA and find your family across all lines of your family tree. There is even a population percentage result with this test.

The test itself involves the identification and matching up of 22 autosomal chromosomes.  This detail allows for up to 5 generations of a person’s family tree to be identified and matched up.

This is just one of 16 different tests that this genetic genealogy testing laboratory can conduct for you involving your DNA. This is the total number from both Y-DNA and mtDNA tests. The price range is from $99 to $559.

The more in depth the testing and more sequences that are identified, the greater the cost will be.

The Family Tree DNA is the largest established genetic genealogy site available for the general public to learn about their past and family tree.

When you go to their website for the first time it might appear a little overwhelming, but simply break it down into what fits your needs.  For instance if you are a first time customer, and a male, then you would most likely want to start with the Y-DNA test.  This method will follow all of your father’s direct male ancestry back to the beginnings of time.  In other words, your father, his father, his father, and so on back to ancient times.

For men or women that are interested in the ancient beginnings of their maternal ancestors you will want to look into mtDNA testing.  This will follow your mother’s mother’s, mother’s, etc. line backwards to show you the ancient group that you belong to as the peopling of the world progressed out of Africa in the beginning of time.

Now in addition to just looking at the two outermost branches of your family tree, FTDNA has developed the unique testing program and genealogy database called “Family Finder” which will  be able to connect you to hundreds, thousands of relatives who have recorded their ancestry with Family Tree DNA and you will be able to discover cousins and distant relatives that you would have never dreamed of before.

Genealogy Research:

Then through the use of good old, tried and true genealogy research you will most likely discover just how you are related.  Look forward to many years of pleasant correspondence and lining up with distant relatives far and wide.

You meet the nicest people through Genealogy DNA Testing.

The genealogical DNA test that is readily available for any one to take has been refined over the years to give accurate and informative information about the ancestral past of the subject. Because of the popularity of this kind of test, the prices have decreased in recent years making the availability of even more results and family lines available for genealogist to use in their work.

The simplicity of the test makes it possible for most anyone to take the sample at their home. This helps to avoid an unnecessary expense of traveling to a certified laboratory and having a technician take the sample.

A sample is taken by rubbing a cotton swab, or a provided paddle type scraper, on a person’s cheek inside the mouth. This collects numerous cells that contains the DNA. This sampling technique is the simplest that can be used. The only decision a person needs to make is how thorough of a test that is to be conducted should be. The more markers that are identified, the more information can be discovered.

There are two distinctly different tests that can be conducted. The Y DNA is for the father’s lineage while the mtDNA is from the mother lineage. With the Y DNA, there are repeating nucleotides that are called Short Tandem Repeats (STRs) that are identified. There are over 100 of these present but the maximum testing usually only contains 67 of them for thorough results.

With mtDNA, the Single Nucleotides Polymorphisms (SNPs) are tested. These are passed down from every mother to her children without mutations. This is a stable DNA that can be traced back in time to which Haplogroup a person originates from. The basic test involves 12 markers but just like the Y DNA, up to 67 markers can be identified and used for analysis.

Depending on the thoroughness of the desired results, a genealogical DNA test can range in cost from just under $100 up to $700. The choice is that of the person desiring the results.

With genealogy DNA testing, a person or family can trace back their heritage or lineage to who their ancestors were and where they came from. The way this is accomplished is by examining the different nucleotides on the DNA sample and where they are located on the strain.

Unlike other DNA testing results, this is for ancestral heritage only. The DNA testing for medical purposes that include genetic diseases and disorders is not what this test will uncover.

The testing of DNA for genealogy purposes involves identifying certain nucleotide markers from the current sample with those in a historical database that contains ancestral populations from the distant past.

For males, both the father’s and mother’s ancestral lines can be explored, while for females, only their mother’s ancestors can be uncovered. This is because males have both the Y DNA chromosome and the mt DNA chromosome.

The Y chromosome is the genetic marker that is passed down from father to son and is unchanged. This is the path that can be followed for both the surname ancestral path and genetic markup. If a female wishes to know their father’s lineage, a sample from their brother, father, uncle, or grandfather can trace back the Y chromosome line of heritage. In time, this genetic marker changes slightly so perfect matches over thousands of years is unobtainable.

The mtDNA is the genetic marker every mother passes down to their children. This is for both males and females the woman gives birth to. Unlike the Y DNA, the mtDNA does not change over time and perfect matches with samples thousands of years old is very common.

This is a general description of the potential a person can expect when they have genealogy DNA testing done when looking into the past history of their family.

Genealogical DNA Testing keeps advancing and now the latest types of autosomal testing can even help discover your level of Native American Ancestry.
