DNA 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 initials stand for deoxyribonucleic acid. Replication is the unique thing about DNA since it can be passed from one generation of a species to the next. This self replication feature is what makes it possible to use DNA as a form of testing for various relations in living organisms.
One can deduce a lot of information about human beings from DNA testing. The most common of them is paternity testing. This is because there are very many situations in the world that require for testing for the paternity of a child. DNA paternity tests are tests done on a child and a man to test whether the child is actually a biological child of the man. DNA testing is an almost 100% certain test for paternity in the world today.
There are other phenomena about human beings that can be established using DNA testing. They are important phenomena but are not as popular as paternity tests. One can establish the ancestry of human beings using DNA tests. Ancestral information can be well established by using genealogical tests. This type of test usually examines a person’s genome after unwinding the strand of a DNA chromosome. Unwinding of the strand must happen for the test to be done.
There are different findings that can be made from genealogical DNA testing. Ethnicity is the first thing that can be known through genealogical testing. 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. Ancestry can easily be deduced by establishing tribal lineage.
Ancestry testing can also be used to test fossils. Scientists have been working hard to establish many aspects of the origin of man. Remains of human beings form an important parcel in this investigation. For the information to be complete, DNA testing must be done on such remains to establish any similarities with currently living people. This helps in establishing lineage and 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. What part of the body is used during DNA testing? Blood is the most common specimen used in DNA testing in most parts of the world. Blood is however not the only specimen that can help in DNA testing. It is possible to find out a lot of information about human being relationships by using DNA that has been taken from human hair. Sometimes body fluids such as saliva have been found to have DNA than can also be used in genetic relationships testing.
