Paternity testing is a scientific method used to determine whether a man is the biological father of a child. This process typically involves analyzing DNA samples from the child and the alleged father. The results can confirm or exclude paternity with a high degree of accuracy. The most common type of paternity test is a DNA test, which compares specific genetic markers. These tests can be performed using samples from cheek swabs, blood, or other bodily fluids. Paternity testing is often used in legal situations, such as custody disputes, or for personal reasons, like confirming family relationships.
