Genetic analyses comparing DNA samples from individuals can establish the likelihood of a biological relationship. For example, such analyses can determine whether individuals share one or both parents, or if they share one parent but not the other. This type of testing is often sought to confirm family relationships when birth records are unavailable or incomplete.
Confirmation of biological relationships provides legal and emotional resolution for many. It can help individuals access inheritance rights, understand medical histories, and build stronger familial connections. Advancements in DNA sequencing technology have made these analyses more accurate, affordable, and accessible than ever before, transforming how kinship is established. This scientific approach offers a reliable alternative to traditional genealogical research.
