DNA 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 full meaning of the letters DNA is deoxyribonucleic acid. Replication is the unique thing about DNA since it can be passed from one generation of a species to the next. Relationships among different organisms can be established thanks to the self-replication feature of DNA.
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. Paternity testing involves testing a child and the man separately to find out if the man is the biological father to the child. One can almost certainly rely on the results of paternity tests as the true result.
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 such phenomenon is ancestry testing. This can be done using a genealogical DNA test. The genome of a person is examined form a DNA strand to establish ancestry. Unwinding of the strand must happen for the test to be done.
Genealogical DNA testing can help establish different results. First of all ethnicity can be established. This is basically the tribe from which a person comes from. 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.
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. They use DNA testing to further investigate relationship of such remains with the modern world. Ancestry can thus be established.
The geographical origin of any species can be established by using genealogical tests. It can also give evidence of age of any remains of human beings. 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. 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. Sometimes body fluids such as saliva have been found to have DNA than can also be used in genetic relationships testing.
