BEST DNA ANCESTRY TEST

A long time now, genealogists have been focusing on spoken and paper records to track their family root. In the 21st century, the year 2000 precisely, genealogical DNA testing was brought to light. This paved the way for scientists and family history researchers with a chance to make use of very organized scientific methods ascertain relationships and ancestry.

With comparison to paper records, which might be incorrect, DNA testing is accurate. Before we leap into the best DNA ancestry test, let’s first discuss what a DNA is all about. A DNA is in all living cell. It’s a chemical chain that is long and tells cells how to grow and behave. ¬†DNA is separated into chromosomes in which are divided into genes.

How do you choose the test that’s best for you? There are few different types of DNA ancestry tests. And they are in three different categories namely, y-chromosomes, autosomal and mitochondrial. Each of these types work a little differently and some of their methods are kind of better than the rest in detecting some traits and origins. All the tests start the same with collection of DNA samples. It can be done using a cheek swab, spit sample or chewing gum or special mouth wash. If it’s collected at home, it must be sent to a lab for test.

Autosomal tests take its look at 22 pairs of chromosomes not kind of associated with gender in order to trace the both, patrilineal and matrilineal ancestors. These chromosomes all carry traits from distant relations from the both sides of a family. The data taken from them goes into a database that is used to look for the same patterns among other individuals called matches. Testing companies deeply set thresholds for the length of a DNA strand that constitutes a match.

Determining whether you are related to another specific human-being or to find out if you are related to someone you don’t know is the real purpose of an autosomal test. Based on your matches, and where in the world the patterns found in your DNA are most common, some companies as well make room for ethnicity estimates.

Services testing are often called maternal origin test because mitochondrial DNA is passed from mothers to children. In your body, most cells contain hundreds of mitochondrial or even more. It’s easier to pinpoint differences between two individuals’ tests because mitochondrial DNA contains far fewer base pairs than the few human genomes. The tests can be used to locate ancestral heritage on mothers side, or to find maternal ancestors.

Y-chromosomes tests are unavailable for women, only for men cause women have two X chromosomes. They track patrilineal ancestry as a result, often, they are called paternity tests. They are some of the most accurate test dealing with determining one’s lineage cause the Y-chromosomes rarely changes when it passes from one generation to the other. Also, they can be used to determine if two people are related on their father’s side. Also, how many generations a common relative existed. When it comes to tests for maternal origin, tests for Y-chromosomes can be used to determine ones link to a pre-colonial ethnic group due to haplogroups found in ones DNA. A lot of commercial tests add some or possibly all of these methods in order to give customers a more clear and vast understanding of their lineage. It’s only by understanding the both sides of your family you can get to know your true heritage, and the more data they test for you, the more precise and likelihood of getting the best DNA Ancestry test result you get.
