The Success of Genealogy Research Lies on DNA Testings

Genealogy text

Genealogy research has become even more popular since the pandemic. Considering more people were stuck at home with there computers but very little to do. Many people made the decision to do a DNA test. There are approximately 60,000 billion cells found in the human body. These include muscle cells, cheek cells, white blood cells and more. Each of these cells contains the whole genetic information which is the eoxyribonucleic acid, or more commonly know to us as DNA .

Let’s Get Techie

The nucleus inside the cell holds the DNA or chromosomal DNA that consists of Y chromosomal DNA, X chromosomal DNA, and autosomal DNA. The external part of the nucleus holds mitochondrial DNA (mtDNA). The autosomal DNA comes from both the mother and the father, Y chromosomes is inherited by a son from his father, and mtDNA comes from the mother only.

There have been many genealogy research advancements made in testing DNA to meet various areas of interests. For example, the most common uses of DNA are related to finding criminals and proving paternity. But today, genealogy researchers also use DNA testing.

For many years, genealogy has become an important element of our society and a favorite hobby of many enthusiasts.

It can be exciting at times, tracing our family roots. Although genealogy research may be rewarding, it can also bring frustrations even to expert genealogists. As the family historian, I have hit many brickwalls!

It can also be very time consuming when doing paper research. If not stored properly, it can also lead to illegible and damaged documents. But, DNA testing provides quick results without questioning its authenticity or quality. Moreover, the genetic genealogy results can endure the tests of time.

Maternal Heritage

  1. Tracing the “maternal heritage” of a person is called Mitochondrial testing.. The mtDNA testing is very important since genealogists are mostly females. Maternal lines are most often lost because of changing their surnames when the female marries, but in this manner, they can learn and trace their maternal ancestry.

Advances in DNA Technology

Through the years, there have been many advances made in understanding genetics and using these laboratory techniques. This has been a gigantic step for a person to identify maternal lineage through mtDNA tracing services. The distinct mtDNA of person is analyzed and compared to the databases of other samples of mtDNA worldwide, revealing information about the lost ancestry.

The mtDNA remains nearly unchanged even for so many years. You can share the same type of mtDNA with your mother, maternal grandmother, and maternal great grandmother. The same exact mtDNA code can track your direct maternal lineage way back from the time where mtDNA code’s natural mutation occurred. I know this sounds a little techie, but it’s still exciting to a genealogist!

Women who are living today can trace their origins back 150 thousands years ago through natural mutations or mitochondrial eve. In connection with matrilineal descent, Eve is the common ancestor. But it doesn’t necessarily imply that Eve is the only woman who lived in that era. There were also other women alive but only the lineage of Eve has survived.

Paternal Heritage

  1. The Y chromosomal DNA testing, or “Paternal Heritage”, is the most common used form of genetic genealogy testing. Some people can even trace if a deceased man is related to them by conducting this test.

Like the mtDNA, our Y chromosomes can be also traced back from one prehistoric father, Adam. The DNA mutation of the first Y chromosomes naturally occurs over many generations. Determining the present Y chromosomes can trace your paternal lineage through searching the Y database worldwide.

Genealogists can find out if two people are related when they have similar surnames through Y chromosomes testing. In most of our cultures, surnames or family names are inherited by children from their fathers like the Y chromosomal DNA.

A successful genealogy research relies on DNA testing and its usefulness has proven as time passed by. Possibly the most popular DNA testing is through Ancestry.com but there are may others that you can find online.
