Genetic Testing or DNA testing is a fairly recent development because of advances in scientific knowledge that has many and varied uses including paternity testing, testing for various genetic diseases during pregnancy, or for forensic investigations.
The First use of genetic testing is known as paternity testing and can be used to confirm who the biological father of a child is. Genetic testing – DNA test in this case can be accomplished through collecting a sample of their father’s, mother’s and child’s DNA that are then compared at different points. This way of verifying paternity is far more precise than older methods and can be painless as a DNA sample could be collected from a swab of the cheek.
Another use of In this case portions of the Y chromosome that do not tend to switch through the generations will be compared to others. Individuals that have a common ancestor will reveal similar characteristics in certain areas of the particular chromosome and so can help establish ancestral lines.
This is also associated with genetic testing for ancestry, or What proportion of each race group you’ve got in your DNA. By doing an ancestral genetic evaluation through labs offering this service or house packs to check your ancestry you’re able to ascertain your race history.

Many diseases may be associated with an abnormality in the Genetic testing – DNA test that may be detected through DNA testing so as to warn the parents of the possibility so they can do what’s best for their own child.
There are a number of applications for genetic And testing for potential health problems in an unborn child. Genetic Testing is usually noninvasive and painless as DNA swabs can be obtained In the cheek for comparison rather than having to take blood. These DNA swabs are then examined in a lab to compare different DNA Segments and so determine the outcomes of the aforementioned tests.
