How to Use DNA Genealogy to Discover Your Ancestors

DNA Genealogy has opened up the possibilities for helping more and more people connect with each other. New types of DNA genealogy tests are now available to the public, through which it is possible to locate long lost family members. It is indeed possible to simply search one’s surname in a given DNA database and resultantly locate other family members that have matching DNA.


The Modern Day Advancements

With modern day advancements and technologies in the field of genealogy, DNA testing has been taken to new heights. Whether you need to find out more about your own ancestry or wish to trace your roots, you can definitely come across a DNA test that can help you out.

Genealogy is the name given to the study that determines the roots of people. DNA tests are the simplest and most useful way out when all kinds of family document researching and record searching fail. What’s more, DNA tests are the best method of knowing about descent or genetic genealogical connections.

If you wish to know your own ancestral roots, you can get DNA tests carried out on you and your family members. Testing relatives are essential in knowing about your ancestors. In fact, there are higher chances of success if you have more people who can get tested in your family.


The Wonders of Modern DNA Genealogy Testing

Modern DNA testing is able to pinpoint the location of your ancestors. The DNA allows us to know if we are 10% Hispanic or 30% African American. Genetic ancestry testing is offered by several companies and organizations. Examination of DNA variations can provide clues about where a person’s ancestors might have come from and about relationships between families. Most companies provide online forums and other services to allow people who have been tested to share and discuss their results with others, which may allow them to discover previously unknown relationships.

Types of Genealogy DNA Tests

While it is better to consult any private facility for services, you can also locate your family members through tests that are doable at home. With these tests, you will get accurate results regarding your ethnic heritage, ancestral history, and family background.

With tests, you also have the ability to find out new family members and relatives you never knew existed. Basically, there are two types of tests available for people who wish to locate their relatives through DNA testing. The tests are described below:

mtDNA Tests: The mtDNA tests are a great way to find out about your family ancestry. These mtDNA tests are the ones that help you determine your maternal ancestral lineage. The cytoplasms that are found in the human body’s each cell contain mitochondria. This mitochondria remains unchanged (or changes quite slowly). It passes down from generations through the mothers. This can simply be explained by the following definition:

Your mother has the same mtDNA as all her children, including you. This mtDNA is the same as your grandmother’s, and her grandmother’s, and so on. The mtDNA can only be passed on by females.

Y Line TestsAlso known as Y-DNA tests, these tests help determine the paternal lineage of your ancestry. It can only be carried out on males. This is mostly because the Y chromosome (for which these tests are known) is only passed down by males from generation to generation. If two individuals share Y chromosome markers in their family line, their close relatedness will show. These Y line tests are frequently used for proving lawsuits related to paternity.


Autosomal Test: This relates to DNA chromosome pairs which have no gender influence. These are DNA which is passed randomly from both parents. While it is not exact enough to be used in law or paternity cases in the way Y Line tests might be, it does have the ability to show relationships between people. This type of DNA test will show 5th cousins and more as DNA matches, therefore allowing technology to provide possible DNA matches and find long-lost cousins. There is also a degree of triangulation involved in the test, in which more people’s DNA is added until a relationship can be figured out between the matching people. This allows for increased discovery.


Using DNA Genealogy to Find Family

Firstly, you will need to carry our a DNA test. This is an easy process, simply order your DNA kit, complete the home test and post back the test sample. Your DNA will be compared with 800,000 autosomal genetic markers tested, 862 reference populations analyzed, 36 gene pools analyzed. Your results will be with you in around 6 weeks. Results will contain a % ethnicity (gene pool) breakdown as well as your ancestor’s migrations routes.

Secondly, you can take your DNA results and upload them to websites such as to see if cousins can be found. The process could not be easier, nor more rewarding for that matter.
