Genealogy Tests

Genealogy tests are tests in which people interested in family history take to learn historical documentation or to go beyond what they can learn from relatives.

Examining DNA variations provide clues about where an individual’s ancestors may have come from and as well deals with relationships between families. Often, specific patterns of genetic variations are shared between people of particular backgrounds. The more patterns of variations two persons share, the more closely related they are.

There are three types of genealogy tests, Mitochondrial DNA, Single Nucleotide Polymorphism, and Y-chromosome.

Mitochondrial DNA: It identifies genetic variations. Cell structures called mitochondrial as well have a little amount of their own DNA called mitochondrial DNA, though most DNA is packaged in chromosomes within the cell nucleus. Males and females have mitochondrial DNA, passed on from their mothers, meaning, this type of testing can be used by either sex. About the direct female ancestral lines, it provides information. This genealogy test can be useful for genealogy because of the way surnames are often passed down, it preserves information about female ancestors that might be lost from the historical record.

Single Nucleotide Polymorphism: All through an individual’s entire genome, these genealogy tests evaluate large numbers of variations (Single Nucleotide Polymorphisms). With that of others who took the tests to provide an estimate of an individual’s ethnic background, the results are compared. An example of the pattern of SNPs (Single Nucleotide Polymorphisms) may show that an individual’s DNA ancestry is approximately fifty percent African, twenty-five percent European, twenty percent Asian, five percent unknown. Because of the limitations of Y-chromosome and mitochondrial genealogy tests results which tends to represent only one or single ancestral lines instead of capturing the total ethnic background of a person, genealogists prefer the use of this kind of tests.

Y-chromosome: Passed only from father to son, variations in the Y-chromosome can be used to explore ancestry in the direct male line. Because females don’t have Y-chromosome, Y-chromosome tests can be done only on males. Sometimes women who have interest in these kinds of tests recruit a male relative to have the test done. In the same pattern as are family names in a lot of cultures, Y-chromosome is passed on. Whether two families with the same surname are related, Y-chromosomes test is often used to investigate.

Genealogy tests are offered by a lot of companies and organizations. Most of these companies make room for online forums and other services to let people who have been tested discuss their results with others, and it might as well let them find out previous unknown relationships.

On a wider note, scientists use combined genealogy test results from many individuals to explore the historical background of populations as they rose, migrated and mixed with some other groups.
