DNA Testing: How it helps With Genealogy
DNA testing has been getting their share of popularity these days, especially for people who want to discover who their ancestors are and where they come from. This test will find out your paternal origin; and therefore helps find out your genealogy by determining ancestry and proving relationships. DNA is what makes up our genes, passed down from generation to generation, and they are often used for testing paternity. People often get into this to check on their ancestry and complete their family tree, a new passion people engaged in nowadays.
DNA testing is a technique used by forensic experts to help identify individuals basing on the profile of their own DNA. There are many things that DNA testing can do to help determine relationship between persons from one to the other. It can provide some clues regarding your ethnic lineage. This can specifically give pointers as to what tribal or cultural race you belong. It can also determine whether you are related to any other living person and will readily know if these persons are your relatives or not. Home DNA testing will be able to determine whether you and another person or a group of persons had a common ancestor and will tell you if you are related to a person or persons having the same surname as you are. You will be surprised at some outcomes of these tests that sometimes even similar or close to the similar spelling of surnames of persons are your relatives. The testing will also find out that the research that you are making on your family tree will be true or not.
One kind of DNA test for genealogy that is available to the public is the mtDNA Test. mtDNA is a kind of DNA which is passed down by your mother to all her children and this does not get mixed with other DNAs. Therefore, it is a good determinant of your mother’s side’s ancestry since hers is the same as your mtDNA which is also the same as the mtDNA of her mother, and is again the same as her mother, and so on. It takes a long time for it to be changed therefore, if two persons have matching mtDNA’s, the chance of their sharing a maternal ancestor is very high. However, it is difficult for the test to determine whether the common ancestor is a recent one or one that dated back to hundreds of years.
The Y Line Test is a DNA Test that has recently been famous because of many people wanting to trace their own ancestry. This is only done on males since the chromosome is being passed down through the male line, which means from the father to the son. The shared markers in the Y chromosome will tell if two male individuals are related to each other through an ancestral bond or whether groups of people are related with each other on the paternal side. This is used by many people who have a similar or same surname.
DNA testing, or home DNA testing done at home, is now commonly available and people who want to avail of these can now submit their DNA sample to be able to trace their roots easily at an affordable cost.
