Unwrapping DNA for Ancestry Testing
Science has enabled the DNA of human beings to be tested for various reasons. The term DNA actually refers to a part of chromosomes of living organisms. The full meaning of the letters DNA is 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. One of such things is paternity of a child. The number of cases that need paternity tests make this type of DNA testing quite popular. Tests for paternity basically seek to establish if a man is biologically the father of a given child. One can almost certainly rely on the results of paternity tests as the true result.
It is possible to establish other relationships of humans using DNA. Though not common, these phenomena are very important about human beings. Ancestry is one relationship that can be established using DNA testing. A genealogical test is the best suited to give such ancestral information. The genome of a person is examined form a DNA strand to establish ancestry. DNA strands are usually unwound during testing.
Several results can be deduced from genealogical DNA tests. Ethnicity is the first thing that can be known through genealogical testing. This is basically the tribe from which a person comes from. Tribe refers to lineage descent from common ancestry. Establishing tribe leads to ease of unmasking ancestry.
Ancestry testing can also be used to test fossils. DNA testing has been vital in establishing origins of mankind scientifically. By locating any remains of people in different locations on planet earth, they can have leads to such information. Such fossil remains give ideas about how those people of the past related with modern day human beings. Such facts can then lead us to conclusive information about ancestry.
Genealogical tests can also help in detecting geographical origin of a species. It is also possible to find out how old fossil remains of human beings are by employing the genealogical DNA testing technique. So, which part of a human body can be used during the DNA testing process? Blood is the most common specimen used in DNA testing in most parts of the world. It is not blood only however that can be used to deduce DNA encoded information. 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.
