DNA testing is commonly used for paternity, medical, genealogy and criminal cases. However, more can be achieved by this scientific approach. It is amazing what science can do these days. DNA testing can actually uncover an ethnic mix, distant relatives and discover new history about a person’s ancestry.
Genetic experts can provide individuals with all these details about their family history and genetic traits by analyzing aspects of saliva, hair, skin and blood samples. DNA tests are well known to produce accuracy of the test results. By methods of fingerprinting and profiling used for DNA tests, genetic experts can identify people and their unique traits.
DNA testing is used in a number of ways:
DNA is unique for every individual. People inherit DNA from their biological parents. DNA testing is known to be an accurate method for proving biological relationships. It can help in inheritance rights, and maternity and paternity proof. This has helped identify biological fathers of young children with 100% accuracy and can also determine if the father is not the biological parent.
It works the same for proving maternity. Apart from this, DNA analyzes an individual’s genes and can determine the genes inherited from parents or ancestors such as hair color, natural talents or facial features. Through DNA tests, genetic experts can explain the traits passed from parents to their children.
2. Forensic and criminal cases
DNA has been successful in identifying suspects or victims in a criminal investigation. Each individual has a unique set of DNA such as fingerprints or hair follicles. These become evidence at the crime scene. This evidence is provided to scientists who can analyze and compare DNA helping criminal prosecutors to determine the individual guilty of the crime. It is used to analyze patterns or connection of cases as well. Results can be inputted into a database to identify the criminal.
DNA testing has been proven to solve cases quicker and ensure the right person is reprimanded. In recent years, DNA tests have helped to conclude unsolved criminal cases or release individuals wrongly convicted. It is used as evidence during court cases and can be the only precise evidence to solve the case. The use of DNA evidence has been questioned on its accuracy in the use of court cases, but this evidence is the best way to link the criminal to the crime.
DNA testing has revolutionized the way people discover family ancestry. Today, with the advancements in DNA testing, people can learn more about their ancestry family tree and origins. It makes individuals unique by determining where they really come from. One of the advantages of DNA testing is that it can connect people with new relatives across the world, building their family tree.
It can help to reveal ethnicity going back multiple generations. It reveals ethnic groups as well as the geographic regions the individual originated from. Through advance DNA technology, genetic experts use an individual’s DNA test to search a global network for people with the same DNA. They can trace family lines back 500 years. Anyone can take the test and get answers regarding their genetic heritage.
4. Defects and diseases
Genes can influence the risk of certain disorders, infection or sickness. Through DNA tests, genetic experts can uncover certain birth defects and diseases. Genetic DNA tests are done using small sample tissues from the body. Using blood from the mother and saliva from the father can determine if an unborn child has any abnormalities and health problems. Diseases have genetic components. DNA tests determine the genetic disease passed from one generation to the next. A prior detection of these disorders or diseases can result in an early diagnosis and prompt treatment to reduce symptoms.
