Confirmation of a biological father-child relationship through DNA analysis is achieved when genetic markers align between the tested individuals. For example, a match in specific DNA sequences strongly indicates a paternal link. This scientific process provides a definitive answer to questions of parentage.
Establishing paternity holds significant legal and social ramifications. It can influence child custody arrangements, child support obligations, and inheritance rights. Furthermore, it offers a foundation for building familial relationships and understanding personal medical history. Advances in DNA technology have made these tests increasingly accurate and accessible, transforming how paternity is determined, compared to historical methods that relied on less reliable indicators like blood typing.
