It is normal to think about our biological ancestry. Some families are fortunate to have plenty of records detailing their ancestry. Unfortunately, most of us lack access to such thorough records about our ancestors. However, modern genomics has made it possible to take a swab sample in the comfort of your home, perform a DNA test, wait a few weeks for the findings, and learn everything there is to know about your ancestors.
What is genetic genealogy?
Genetic genealogy develops family history profiles that could be biological connections between or among individuals. It involves combining DNA test findings with conventional genealogical techniques. The process can determine the types and intensities of various biological relationships between or among individuals.
Professional genealogists use genetic genealogy to solve family history like locating the biological parents of adopted people or finding out the true male ancestor in a non-paternity event.

Types of DNA tests used by genealogists
A DNA sample contains information from three different sources.
Y-chromosomal DNA (Y-DNA)
Y-DNA is present only in male DNA samples that provide information on patriarchal descent. This testing can only be performed in males since females do not have Y-chromosomes. However, women who wish to take this type of test can ask their male relatives to help them.
Mitochondrial DNA (mtDNA)
mtDNA is present in both genders and provides information on matrilineal ancestry. It is transferred from a mother to her child. People can learn about their genealogy through their direct female ancestral line through this type of DNA testing.
Autosomal DNA (atDNA)
atDNA gives information on both patriarchy and matrilineal ancestry. This type of DNA testing examines your entire DNA, excluding the Y-DNA and mtDNA. It provides accurate results for ancestry matches that are very useful for genealogists to determine your biological ancestry.
Limitations of DNA testing
Autosomal DNA (atDNA) is preferred to identify ancestors within the most recent 5-7 generations of a family tree. This is because the signal of autosomal DNA for shared ancestry is weaker than it is in near relatives which makes it impossible to distinguish precise relationships other than similar ethnic affinities by 5-7 generations of separation.
mtDNA changes rapidly whereas Y-DNA changes very slowly. Both mtDNA and Y-DNA tests are used for identifying the migration path of an individual’s ancestors along an exclusive mother’s line and father’s line.
Going through archives and ancient records was a time-consuming process that was not possible for everyone. DNA testing under genetic genealogy made it simple to take a genetic test and determine your precise genealogy and ethnicity. The tests provides highly accurate results that help genealogists to get through an exact family tree.
