The DNA genealogical testing that is being conducted is producing valuable data for not only the present generation to know, but also future generations to rely on. This is so a family tree can be identified and relatives can be located for the purpose of knowing who you are related to.

The study of DNA and its nucleotides for genealogy is the study of who we are related to and not for the search of genetic diseases. There is testing for medical purposes, but there are different sets of tests that must be conducted for that purpose.

The DNA testing for genealogy has already shown some startling results. One of these examples that made headlines a few years back is that it is possible for 16 million men to have the same Y DNA chromosome as Genghis Khan. It was known that he did have many children and, by some estimates, was 800,000 times more prolific than the average man.  Because of this, about 8% of the men in Asia are of his ancestry, and 0.5% of the world’s population. These descendants came from approximately 12,000 offspring and rape was the typical form of inception he used.

A single ancestor is difficult to trace. What is more common is identify a SNP that is a marker for a specific population. This is how scientists are identifying who has European ancestry and African ancestry.  The greatest challenge is separating the vast mixture that has occurred over time in the world’s population.

To help decipher this mixture, the Admixture test has been developed.  While it is still in its infancy, the results are promising on determining a person’s ancestor if their haplogroups are distant enough to be distinguishable.

With the increased use of DNA genealogical testing, more knowledge will be attained about our past for future generations to learn from.
