It is interesting to note that technological advances in DNA testing have created a marketplace for bioanalysis. This subsection of analytical chemistry measures the biotics (DNA) in biological systems. Recent advances in the science of DNA have allowed scientists to uncover many fascinating components of an individual’s biological makeup. Many genealogical societies and organizations have taken these advances in DNA testing to find out more about their ancestors.
The Past: DNA Testing
In the recent past DNA testing was only conducted to determine paternity and to test for hereditary diseases. In the medical field, DNA testing has made a huge difference providing doctors and other medical professionals the ability to fight disease head-on. It has also provided many people with the tools they need to make intelligent decisions about their health and well-being. Paternity tests are important to help doctors determine treatment options and save lives.
The Present: DNA testing
DNA testing and ancestral mapping have become very popular recently due to genealogical promotions. These promotions make it seem that someone can literally find out their ancestors through their DNA. It is understandable for genealogical organizations to take advantage of this new technology. DNA testing has progressed to the point that there is accurate documentation for people living over a thousand years ago. The science behind DNA testing is fascinating.
Genealogical organizations have been able to pinpoint with increasing accuracy the region of birth and map out where our ancestors came from. There are five popular genealogical DNA testing organizations. The most popular genealogical DNA testing sites are Ancestry DNA and FamilyTree DNA. Both of these sites offer chromosome analysis through a series of tests. Autosomal DNA tests provide answers to characteristics that all family members share in common. The YDNA tests analyze only the Y chromosomes that are inherited through the paternal line. The mtDNA tests cover mitochondrial DNA through the maternal line.
The Benefits of DNA testing
The new advances in chromosome analysis have created many benefits for researchers in the medical field. Important discoveries have been made through DNA analysis that potentially cured diseases that have been plaguing society for ages. DNA testing provides information on gene mutation and susceptibility to certain diseases.
DNA testing can help individuals make intelligent decisions to change their lifestyle to correct gene mutations or discuss treatment options. For many adopted individuals, DNA testing provides answers to questions about their current medical conditions. Genetic testing provides doctors with the tools they need to address medical issues and provide accurate treatment options. It is important to note that genetic testing isn’t as yet a hundred percent accurate. Newborn babies however with genetic mutations often can get these mutations fixed.
The combination of DNA testing and ancestral mapping
The newer technologies have made it possible to combine ancestry mapping with DNA testing. One of the biggest ancestral mapping organizations provides detailed information on a person’s roots and heritage. Some genealogical societies utilize this technology to pinpoint their ancestors.
