Unwrapping DNA for Ancestry Testing
The DNA of human beings can be put under test scientifically so as to find out certain information about people. The term DNA actually refers to a part of chromosomes of living organisms. The initials stand for deoxyribonucleic acid. DNA can replicate to the unborn young one of a living organism of the same species. This self replication feature is what makes it possible to use DNA as a form of testing for various relations in living organisms.
A DNA test can help to unearth many things about living organisms especially human beings. Among this things is paternity tests which are very common. Cases that require paternity testing in the world are many hence the popularity of this type of DNA testing. Paternity testing involves testing a child and the man separately to find out if the man is the biological father to the child. DNA paternity tests are actually very reliable the world over.
It is possible to establish other relationships of humans using DNA. Some of these relationships are not common though quite important. Ancestry is one relationship that can be established using DNA testing. Ancestral information can be well established by using genealogical tests. The genome of a person is examined form a DNA strand to establish ancestry. DNA strands are usually unwound during testing.
There are different findings that can be made from genealogical DNA testing. The first one is ethnicity. Tribe is actually the other word formally used for ethnicity. It refers to people of common descent who have one unifying factor such as a common language. Having established which tribe one comes from, it is then easy to use the information to establish the ancestry of the person.
Ancestry testing can also be used to test fossils. The origin of man has been an ongoing investigation in which scientists use DNA testing to find out more about it. By locating any remains of people in different locations on planet earth, they can have leads to such information. They use DNA testing to further investigate relationship of such remains with the modern world. Ancestry can thus be established.
Genealogical tests can also help in detecting geographical origin of a species. The age of remains of human beings can also be established though with approximation from such genealogical DNA tests. So, which part of a human body can be used during the DNA testing process? Most countries in the world use blood as the specimen for any kind of DNA testing. Blood is however not the only specimen that can help in DNA testing. In many cases for example human hair has been used to carry out DNA tests about different aspects correctly. Scientists have established that one can uses saliva as well as other body fluids to carry out DNA tests.
