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 initials stand for 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.
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. This is because there are very many situations in the world that require for testing for the paternity of a child. 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.
There are other phenomena about human beings that can be established using DNA testing. Some of these relationships are not common though quite important. Ancestry is one relationship that can be established using DNA testing. 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. For this to happen, the strand is unwound at a specific position.
Several results can be deduced from genealogical DNA tests. First of all ethnicity can be established. Tribe is actually the other word formally used for ethnicity. Tribe refers to lineage descent from common ancestry. Establishing tribe leads to ease of unmasking ancestry.
Fossils can be tested using ancestral DNA testing. 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. 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. 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. 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. Sometimes body fluids such as saliva have been found to have DNA than can also be used in genetic relationships testing.
