| − | A '''paternity test''' is used to ascertain who is the [[father]] of another person. It is frequently done by [[DNA]] analysis of the [[child]] and the possible father. Since a person's DNA is the same in all of their cells, DNA testing can be done with a [[blood]] sample, a swab of [[skin]], or a lock of [[hair]]. A comparison of two people's DNA sequences will indicate the extent to which they are biologically related. | + | A '''paternity test''' is used to ascertain who is the [[father]] of another person.
