DNA Testing: Know Your Ancestry
In a world where it is extremely hard to distinguish between two human beings, DNA Testing does just that. Literally speaking, a DNA test done on two people will significantly indicate that the two people are indeed different in case of genes. What this does is it attributes the results of DNA Testing to events which require the DNA of the person responsible for the event, to be tested. As an example, let us take the case of a person who had a case of not knowing who his father was. This person could have had a complicated time trying to figure out who his father would be. Fortunately, he went for a DNA Test on himself and based on the results from the DNA Test, within a month's time, he could locate his father with whom he had estranged since birth.
The above mentioned case is just an example where DNA Testing can be useful. The exhaustiveness in testing and the basic concept of science which says that the DNA samples for a person is unique to him has allowed DNA Testing to be a very important and flexible tool in criminal cases, human identification cases, and in more complex terms, cloning. A typical DNA Testing is further divided in to Y-Chromosome Testing and Mitochondrial DNA Testing · Y-Chromosome Testing - Y-Chromosomes are inherited by a son from his father. Thus the Y-Chromosome test is extremely helpful in determining a man's ancestry. Segments of DNA are looked at closely with the help of a microscope to understand genetic patterns. · Mitochondrial DNA Testing - Much like how Y-Chromosome testing is to determine a man's paternal ancestry, the Mitochondrial Testing allows one to determine a person's maternal ancestry as the DNA in human mitochondria is inherited by a son or a daughter from their mother, generally speaking. Though there have been variations to this suggestion, the study of genetics has proved that mitochondrial DNA Testing is indeed the way to determine one's maternal ancestry. For us to understand the whole concept of DNA Testing in more clear terms, we need to get fully acquainted with genetic terms like STR Markers - Repeating set of nucleotides, SNP Markers - Changes to a single nucleotide, Haplotype - Results from the study of STR Markers. DNA Testing is doubly as complex as it sounds and we have specialized companies doing the function of DNA Testing, whose services you can avail of should the need arise. |
