It's impossible to definitively determine paternity without a DNA test. While there are some traditional methods, none provide conclusive evidence.
Here are some methods that were used in the past, but are not considered reliable today:
- Blood type analysis: This method can eliminate some potential fathers based on blood type incompatibility, but it cannot confirm paternity.
- Physical resemblance: While children often share physical characteristics with their parents, these resemblances can be misleading, as they can be common traits within a family.
- Legal documents: Adoption papers or legal acknowledgments of paternity can be used to establish legal parentage but may not reflect biological reality.
Modern methods:
- Ancestry DNA Tests: While these tests don't definitively prove paternity, they can help identify potential relatives and suggest possible connections.
- Genetic Genealogy: This approach combines genealogical research with DNA testing to identify potential family members and establish relationships based on shared DNA.
However, only a DNA paternity test can provide definitive proof of biological parentage.
