How to check if a father/mother is a biological father/mother?

Private DNA labs allow today to check your DNA and also check whether your father or your mother is really your biological father/mother. A daughter or a son shares roughly 50% of its DNA with the father and 50% of DNA with the mother.

Consequently, if you test your DNA and your father DNA or mother DNA, it is possible to know how much DNA is shared between the parents and the infant.

Two DNA test labs provide everything you need to get the result of shared DNA.

  • 23andme.com: Two test kits should be ordered. You have to spit a significant amount of saliva in a test tube. Your father and your mother have to provide saliva too to compare the DNA to them. Each of you will have an account where you check the results. Once the results are here, a member area on 23andme.com allows you to check the closest DNA relative to yourself. If everything is correct, at the end your father or your mother should appear on the list with other DNA relatives. Find a screenshot below of the DNA relatives category.

Then you will put this little toothbrush in a test lab and send it back to the lab. familytreedna.com has also a software which will company DNA results from different users and show the result in a category called “Family Finder” & then “matches”.
