The analysis of genetic material extracted from hair samples to establish a biological father-child relationship offers an alternative method when traditional DNA sources are unavailable. For instance, if buccal swabs or blood samples from the alleged father are inaccessible, a hair strand containing the root can potentially provide the necessary DNA for comparison with the child’s genetic profile.
This method provides a valuable solution in situations where conventional paternity testing is impossible. Its benefit lies in its non-invasive nature and the potential for sample collection without the direct involvement of the individual being tested. Historically, while considered less reliable due to potential DNA degradation and the possibility of contamination, advancements in DNA extraction and amplification techniques have improved the accuracy of hair sample analysis for relationship verification.
