Unwrapping DNA for Ancestry Testing
Science has enabled the DNA of human beings to be tested for various reasons. A part of chromosomes found in living things is actually what is referred to as DNA. The initials stand for deoxyribonucleic acid. It is a component of chromosomes that has the ability to self-replicate from one generation of the organism to the other. Replication enables people to be able to use DNA as a method for testing for relations withing living beings.
A DNA test can help to unearth many things about living organisms especially human beings. The most common of them is paternity testing. The number of cases that need paternity tests make this type of DNA testing quite popular. 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.
Other aspects about human beings can be established by testing 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. This type of test usually examines a person’s genome after unwinding the strand of a DNA chromosome. DNA strands are usually unwound during testing.
There are different findings that can be made from genealogical DNA testing. First of all ethnicity can be established. Ethnicity in this context refers to the tribe. Tribe refers to lineage descent from common ancestry. Ancestry can easily be deduced by establishing tribal lineage.
Fossils can be tested using ancestral DNA testing. DNA testing has been vital in establishing origins of mankind scientifically. Remains of human beings form an important parcel in this investigation. They use DNA testing to further investigate relationship of such remains with the modern world. This helps in establishing lineage and ancestry.
Ancestry testing can establish geographical origin of a species. It can also give evidence of age of any remains of human beings. 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. It is not blood only however that can be used to deduce DNA encoded information. 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.
