Investigating Heritage by Testing DNA
It is possible to test human DNA to establish different aspects using science. DNA is basically a component of chromosomes found in almost all living things. 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. Replication enables people to be able to use DNA as a method for testing for relations withing living beings.
One can deduce a lot of information about human beings from DNA testing. The most common of them is paternity testing. 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. 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. One can establish the ancestry of human beings using DNA tests. This can be done using a genealogical DNA test. 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.
Several results can be deduced from genealogical DNA tests. Ethnicity is the first thing that can be known through genealogical testing. Ethnicity in this context refers to the tribe. Tribe can be understood in different contexts though in most instances it refers to people with the same ancestry and speaking the same language. Ancestry can easily be deduced by establishing tribal lineage.
Fossils can be tested using ancestral DNA testing. The origin of man has been an ongoing investigation in which scientists use DNA testing to find out more about it. Remains of human beings form an important parcel in this investigation. Such fossil remains give ideas about how those people of the past related with modern day human beings. 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. 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. 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. There are some body fluids like saliva that scientists posit that they can be used successfully to generate enough chromosomes for DNA testing.
