In genetics, a non-paternity event (also known as misattributed paternity, not parent expected, or NPE) occurs when an individual's presumed father is not in fact their biological father. This is a type of misattributed parentage experience (MPE) which can involve inaccurate assumptions made by an individual, their parents, or medical ...
DNA paternity testing is the use of DNA profiles to determine whether an individual is the biological parent of another individual. Paternity testing can be especially important when the rights and duties of the father are in issue and a child's paternity is in doubt.
The following is a list of people who are considered a "father" or "mother" (or "founding father" or "founding mother") of a scientific field.Such people are generally regarded to have made the first significant contributions to and/or delineation of that field; they may also be seen as "a" rather than "the" father or mother of the field.
Questions have been raised about one of the UK’s most well-known fertility doctors after two people whose parents attended his clinic reportedly made the shock discovery that their biological ...

A biological father may have legal obligations to a child not raised by him, such as an obligation of monetary support. An adoptive father is a man who has become the child's parent through the legal process of adoption.

Example calculation of a paternity index. In paternity testing, Paternity Index (PI) is a calculated value generated for a single genetic marker or locus (chromosomal location or site of DNA sequence of interest) and is associated with the statistical strength or weight of that locus in favor of or against parentage given the phenotypes of the tested participants and the inheritance scenario.
