The Uses of Genetic DNA Testing

Genetic testing or DNA testing is a relatively recent development due to advances in scientific knowledge that has many and varied uses including paternity testing, testing for various genetic diseases during pregnancy, or for forensic investigations. In this article, we are going to be discussing some of the uses of genetic testing and how they work.

The first use of genetic testing is called paternity testing and is used to verify who the biological father of a child is. When there is a doubt about who the biological father of a child is this can hold not only implications for the relationship both between the parents and between the father and child but also legal and financial implications (for example, who is responsible for meeting the child's financial needs as they grow up).

Genetic testing in this instance can be done through collecting a sample of the father's, mother's and child's DNA which are then compared at various points. You can also visit online to catch the latest update on DNA testing.

This method of verifying paternity is a lot more accurate than older methods and is also painless as a DNA sample can be collected from a swab of the cheek.

Another use of genetic testing is to help create your family tree and verify family history. In this case parts of the Y chromosome that don't tend to change down through the generations will be compared to others.
