Ancestry Genetic Testing
Are you interested in family history and genealogy? Genetic ancestry testing uses the most modern DNA testing technology to tell you much more than you can learn from relatives or historical documentation alone. Looking at DNA variations can give clues about where your ancestors came from and about relationships between families. People of particular backgrounds often share certain patterns of genetic variation. The more patterns of variation two people, families or populations share, the more likely they are closely related. This information can also help solve mysteries about the source of certain genetically inherited health conditions.
Y chromosome testing. This test looks at variations in the Y chromosomes, which go from father to son, to explore ancestry in the direct male line. Since only men have a Y chromosome, Y chromosome testing can only be done on men. Women who are interested in this type of testing may recruit a close male relative to have the test done. Because the Y chromosome is passed on in the same pattern as family names in many cultures, Y chromosome testing is often used to investigate questions such as whether two families with the same surname are related.
Mitochondrial DNA testing. This type of testing identifies genetic variations in mitochondrial DNA. Just like your body has specialized structures called organs that carry out different functions, each cell in your body has specialized structures, called organelles, that carry out different functions for the cell. Mitochondria are organelles within the cell nucleus that are responsible for producing energy.
Mitochondria produce their own DNA, and that DNA is passed down by the mother, unchanged, to all her children, both male and female. So, a mitochondrial DNA test, can be taken by both men and women. It provides information about the direct female ancestral line. Mitochondrial DNA testing can be useful for genealogy because it preserves information about female ancestors that may be lost from the historical record because of the way surnames are often passed down.
Single Nucleotide Polymorphism (SNP) testing. SNPs (pronounced “snips”), are the most common type of genetic variation among people. Each SNP represents a difference in a single DNA building block (called nucleotides). SNP tests look at large numbers of variations (SNPs) across a person’s entire genome. One person’s SNP test results are compared with those of many others who have taken the tests; the comparison provides an estimate of a person’s ethnic background. For example, the pattern of SNPs might indicate that a person’s ancestry is approximately 50 percent European, 25 percent Asian, 20 percent African, and 5 percent unknown. Genealogists use this type of test because Y chromosome and mitochondrial DNA test results, which represent only single ancestral lines, do not capture the overall ethnic background of an individual.
