									Genealogy DNA: One major discovery
for solving different cases.
In Genealogy DNA, testing is done using DNA to determine genetic
relationship between two individuals. Deoxyribonucleic acid, abbreviated as
DNA, has a unique nature and is passed on from generation to generation.
But, in the process of passing down, some features remain unchanged and
other change dramatically. Due to this, you can easily identify whether two
persons are related to each other or not.

There are two types of DNA tests: Mitochondrial (mtDNA) and Y-
chromosome.

Mitochondrial DNA is present in the cytoplasm of the cell. This type of DNA
is passed on from mother and no mixing is done from the side of father’s
body so it is same as your mother’s mtDNA. It is passed down to both male
and female children. If the two persons have the same mtDNA, this means
that they share the same maternal ancestor.

The Y-chromosomes are present in the nucleus of the cell. These
chromosomes are passed on from father to son and are available only in
males. The chemical markers in Y-chromosomes create a unique pattern
called haplotype. It is used to determine the relationship between the two
male individuals with the same surname. If the y-chromosome matches,
means the two individuals, who have the same surname, share common
ancestors.

In 2000 Bryan Skyes published a study on the subject of Genealogy DNA in
which he used DNA (Y-chromosomes) to determine the relatedness between
two individuals. In this study, experiment was done on 48 men with the
surname of skyes. Four short Tandem repeats were done on Y-
chromosomes: DYS19, DYS390, DYS391 and DYS393. The results found
were amazing! Out of 48, 21 men had same core haplotype and the left over
were just one step away. Bryan Skyes interpreted that these men originated
from common ancestor who lived 700 years ago.

Actually DNA plays a very important role while solving the parental issues
which usually end up in court. Using DNA Genealogy, you can easily
determine the original parents of the child. This test is 100% accurate and
no alterations or duplications can be done. You can also easily determine any
genetic disease and find cure for it (if any).

Using DNA traces scientists can easily get an idea about the person’s family
history. But, he cannot discover the origin of languages, cultures and
families. Numerous people and genetic family trees can be traced with the
help of DNA Genealogy.

Today, in United States, there are 561 Indian tribes which are traced by DNA
testing. People are becoming more and more interested in finding out about
the tribe to which their family belongs. Some people prefer tests in
laboratories while others do it at their home using home kits and send the
samples to laboratories. Some people prefer testing just to check out any
health related issue.

If you have any family issue or want to know about the child biological links,
A DNA test is the thing that cannot be beaten. Genealogy DNA is the biggest
discovery ever done and is used to solve different cases all over the world.
