Genealogical DNA Tests
A genealogical DNA test is a type of a DNA test that focuses on specific locations of a person's genome so that its ability to determine the genealogical relationship and ancestral ethnicity. There are three main types of genealogical DNA test, each focusing on a different part of the genome and used for various types of genealogical research. However, the test results do not give information about diseases or medical conditions.
Carrying out the genealogical DNA test requires a collection of a DNA sample, which can be done through ordering a home test through the best dna test supplier or just visiting a DNA test clinic. The collection is done through various methods like spit-cups, mouthwash, buccal swab or chewing gum.
There are three major types of genealogical DNA test; Autosomal, Y-DNA and mtDNA.Autosomal tests look at chromosomes X and 1-22. The latter are inherited from both parents and other ancestors that are deemed recent. The X chromosome follows a particular inheritance pattern which makes it easy for ethnicity estimates to be included in this kind of dna testing uk. The Y-DNA looks, on the other hand, look at Y-chromosome which is inherited from father to his son, and therefore samples can only be taken by males to find out their direct paternal lineage. Finally, the mtDNA looks at mitochondria which are inherited from mother to child and so can be used to find out one's direct maternal line. The mtDNA and Y-DNA cannot be used for ethnicity estimates, however, they can be used to explore one's haplogroup which is distributed unevenly throughout various geographical location.
The interest in genealogical DNA tests has been associated with an increase in curiosity about traditional genealogy and a person's origin. For those who test for traditional genealogy, they often utilize a combination of mitochondrial, autosomal and Y-chromosome tests. Those who have an interest in personal ethnic origins are more likely to use an autosomal test. However, specific questions about the ethnic origins of a specified lineage may be suited to Y-DNA test or mtDNA test.
Genealogical DNA tests have become popular due to the easy and convenient way of testing at home and their usefulness in supplementing genealogical research. The tests allow an individual to explore with high accuracy whether he or she is related to another person within a certain time frame.DNA tests are assumed to be more scientific and conclusive than searching through the civil records.
