Can DNA tests be wrong?
This is one of the most common ways that a paternity test can be ‘wrong’, although it’s not necessarily wrong, which is why the term ‘false positive’ is used.
If the two (or more) potential fathers of a child are biological relatives, they share DNA, for example: …

For deeper family roots, these tests do not really tell you where your ancestors came from.

What are the steps of DNA fingerprinting?

How accurate is DNA fingerprinting?
Scientists who analyzed data used in DNA fingerprinting say it is extremely unlikely that the technique, if properly performed, would wrongly implicate an innocent person in a crime.
What makes a DNA fingerprint unique?

The individual traits of every person are contained in their DNA. … And this unique sequence in the order of the base pairs makes each person’s DNA unique and different.

What are some examples of DNA fingerprinting?
