A certain uniqueness is encoded in each person’s DNA (Deoxyribonucleic Acid). Our genes, which are made up of DNA, act as a “blueprint” that determines our appearance and other characteristics which are recognizable with the best DNA test kit. At the time of conception, every individual receives an identical set of chromosomes from both parents, making up their unique set of DNA. This forms the basis of a DNA paternity test which uses DNA to prove that a man is indeed the biological father of a child. There has been widespread usage of paternity tests and other methods of establishing familial ties for well over a century. It has replaced blood typing which was a common procedure in the early 20th century.
