How is paternal dna testing done?
Paternal DNA testing provides scientific evidence for people seeking information regarding their paternal family lineage. Both local labs and home testing kits utilize cheek swabs to gather DNA samples.BackgroundSince the advent of DNA testing in 1985, biological material (skin, hair, blood and other bodily fluids) has emerged as the most reliable physical evidence at a crime scene, particularly those involving sexual assaults. DNA, or deoxyribonucleic acid, contains the complex genetic blueprint that distinguishes each person.IdentificationCheek swabs provide human cells to test an individual’s DNA. Paternal DNA testing identifies genetic markers. Several genetic markers, known as short tandem repeats (TDR) occur in specific genetic groups. Paternal DNA is one type of TDR. The Y chromosome does not transfer from father to daughter.LineagePaternal DNA testing provides a method to trace ancestry through DNA mutations and genetic markers.
