Paternity testing is a kind of genetic fingerprinting that can be used to determine the biological father of a child.

Paternity tests are conducted by collecting samples from the child and the possible fathers. The samples are then analyzed for DNA sequences. If there is a match between the DNA sequences, then it means that this person is the biological father of the child.

There are several types of paternity tests available in the market such as home paternity test kits and laboratory tests. Home paternity test kits are cheaper than lab tests but they have their own limitations such as not being able to detect all types of genetic markers and not having a scientific accuracy level.
