Genealogy DNA

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.
