Investigating Heritage by Testing DNA
It is possible to test human DNA to establish different aspects using science. A part of chromosomes found in living things is actually what is referred to as DNA. DNA in full is 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. One of such things is paternity of a child. Cases that require paternity testing in the world are many hence the popularity of this type of DNA testing. 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 paternity tests are actually very reliable the world over.
It is possible to establish other relationships of humans using DNA. They are important phenomena but are not as popular as paternity tests. Ancestry is one relationship that can be established using DNA testing. Ancestral information can be well established by using genealogical tests. Ancestry in a genealogical test is established using genomes from DNA chromosomes. Unwinding of the strand must happen for the test to be done.
There are different findings that can be made from genealogical DNA testing. The first one is ethnicity. 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. Scientists have been working hard to establish many aspects of the origin of man. By locating any remains of people in different locations on planet earth, they can have leads to such information. For the information to be complete, DNA testing must be done on such remains to establish any similarities with currently living people. Ancestry can thus be established.
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? Most countries in the world use blood as the specimen for any kind of DNA testing. However, there are other parts of the body that can be used in place of blood. For instance strands of human hair have been found to contain genetic chromosomes that can also encode ancestry genes. Scientists have established that one can uses saliva as well as other body fluids to carry out DNA tests.
