The Chromosome Y test can determine if any cousins are from the same paternal line.
If in your search for paternity, the doubt is about presumed fathers from the same family, the Y chromosome test will not determine who the biological father is.
However, it can be useful in excluding men from a supposed biological relationship.
The reliability of the Chromosome Y test is:
- For a negative result, 100% reliability
- For positive result, 99.9% reliability
- Me ( Male )
- Alleged cousin
