Establishing biological fatherhood is a legal and personal matter that can be achieved even when the potential parent is unavailable. Circumstances might preclude direct participation in standard DNA testing procedures. This absence necessitates alternative approaches to confirm genetic lineage.
Definitively determining parentage offers significant advantages, including establishing legal rights for the child, providing access to medical history, and solidifying familial bonds. Historically, reliance on physical resemblance and blood typing provided limited accuracy. Modern genetic testing furnishes a far more reliable means of establishing biological relationships, even under challenging conditions.
