If you want to know about Genetic Genealogy then must go through this article. In this content, you will find every detail about it as well as genes. So, move ahead, and in case of any DNA-related difficulties while going through this article then must reach the experts right away.

About Genetic Genealogy

Genealogy Genetics is basically the combination of DNA testing along with traditional genealogy. With the help of this, one can easily identify their ancestors as well as family members. Also, by analyzing the DNA of a person, you can also learn about their ethnic heritage as well as examine genetic markers for disease risk. Along with that, it also helps in finding long-lost relatives.

Recently, the field of Genetic Genealogy has exploded so much. So, DNA testing has become affordable as well as accessible. Thus, if you want to know more about your family or want to trace them then this would be the perfect choice!

Use of Genealogical DNA Tests

The Genealogical DNA tests are basically used in genetic genealogy for determining ancestry as well as genealogical origins. This test is used for comparing the results of the DNA test with those who have already tested. Also, it is used for determining genetic similarities. Along with that, it helps in providing information related to how closely people are related. Typically, the tests are conducted via Ancestry DNA samples which consists of cheek swab or saliva.

Testing companies of DNA Genealogical

There are many companies that offer DNA testing such as;

  • AncestryDNA
  • 23andMe
  • MyHeritage
  • FamilyTreeDNA
  • LivingDNA

Different variety of techniques as well as approaches are used for analyzing the DNA Genealogy samples. It helps in providing the information related to the ancestry as well as family history.

Different Types of DNA Tests With Details

There are three different types;

  • Autosomal (atDNA): It is used for finding the relatives within the past five to seven generations only. It can help one to learn more about their ancestry in detail.
  • Mitochondrial (mtDNA): It is used for tracing the direct maternal ancestry of a person. It is found in the mitochondria of a person.
  • Y-chromosome (Y-DNA): It is used for examining the DNA that is found on the Y-chromosomes. It is passed down from father to son and also, it is used for tracing the paternal ancestry.

Some Genetic Genealogy Definitions

  1. Population Genetics: It is a branch that is used for studying the different frequencies in which DNA occurs. It can be easily done simply by sampling different genomes in the population like blood samples/cheek swabs. The biological origin can be easily predicted with the help of computer algorithms. Also, it uses proprietary calculations for estimating what percentage of DNA comes from particular groups. Thus, it is considered one of the most amazing ways to learn more about family history.
  2. Investigative Genetic Genealogy: With the help of this, you can easily use genetic genealogy to discover unknown identities. It is different from forensics because it depends on the public information. Also, it can be used by law enforcement to solve violent crimes as well as cold cases.
  3. Human Migration: It is studied via haplogroups in the genetic genealogy. Basically, a haplogroup is a genetic population that is used for sharing a common ancestry. Also, scientific studies on genetics have proved that humans originated in Africa before 300 thousand years ago.
  4. Whole Genome Sequencing: It is a time-consuming process and so, its rate is higher than others. With the help of this, one can easily know about health. Ancestry and risk of any disease. This tool plays an important role, especially in research. With the help of this, they can improve disease. Also, will be able to know more about the disease as well as human health.
