DNA Ancestry Testing

The DNA of human beings can be put under test scientifically so as to find out certain information about people. 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. It is a component of chromosomes that has the ability to self-replicate from one generation of the organism to the other. This self replication feature is what makes it possible to use DNA as a form of testing for various relations in living organisms.

A DNA test can help to unearth many things about living organisms especially human beings. Among this things is paternity tests which are very common. 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.

Other aspects about human beings can be established by testing 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. 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. Ethnicity is the first thing that can be known through genealogical testing. 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. DNA testing has been vital in establishing origins of mankind scientifically. By locating any remains of people in different locations on planet earth, they can have leads to such information. Such fossil remains give ideas about how those people of the past related with modern day human beings. Such facts can then lead us to conclusive information about ancestry.

Ancestry testing can establish geographical origin of a species. The age of remains of human beings can also be established though with approximation from such genealogical DNA tests. 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. It is not blood only however that can be used to deduce DNA encoded information. It is possible to find out a lot of information about human being relationships by using DNA that has been taken from human hair. There are some body fluids like saliva that scientists posit that they can be used successfully to generate enough chromosomes for DNA testing.
