This means that mtDNA and Y-DNA tests can allow an individual to trace their ancestry back through a haplogroup for centuries. Y-DNA and Mitochondrial DNA are generally much more objective and allow for the discovery of relationships along a strict female line and a strict male line. Autosomal tests are also widely used to estimate your ethnicity composition. Autosomal tests are great for finding out who you are related to through DNA matching. These three methods are autosomal, mitochondrial (mtDNA), and Y-DNA. Each method looks at a different part of the genome and can be useful for various kinds of genealogical research. Three Principal Types of DNA Genealogical TestsĭNA can be gathered from the nucleus of a cell, from the Y-chromosome, or the mitochondria of a cell. This allows specialists to make accurate ethnic and genealogical conclusions. These libraries are in many cases available for sample comparison by DNA specialists and in some cases are even available to the general public. The DNA data gathered from samples will be cataloged and then run through algorithms that compare the information in your genetic code to other data samples found in large DNA libraries and their own DNA database (reference population).
This can help determine ethnicity, lineage, health factors, traits, and much more. Once a DNA sample is broken down into a digital genetic code, it can be examined and compared to other DNA samples. This saliva sample is then mailed to a laboratory where it is examined by specialists and then broken down into a sequence of letters that make up your genetic code: A, C, G, and T. When using a mainstream DNA testing kit like the ones offered by MyHeritage DNA, your DNA sample will be gathered through the use of a saliva cheek swab. Some DNA testing services are also useful in determining certain predispositions to common ailments or diseases, uncovering unknown genetic traits, and determining other fascinating physical characteristics.ĭNA testing involves sampling your genetic material and breaking it down digitally. With DNA testing, you can discover more about your ancestry, family history, genealogy, lineage, family tree, and estimate which ethnicities are most prevalent in your genetic makeup. DNA testing services can be useful for a variety of reasons.
