My fianc had two paternity test did on two kids (one mother). Also, if a mother of the two siblings was included after and the percentage went down to a 13.8% what does that mean?

These numbers calculate to give the probability of paternity. Although genetic testing can provide important information for diagnosing, treating and preventing illness, there are . The results showed he was excluded with 0% probability.I have since done another DNA with the other guy and it is showing that there is gene mutation. Its much easier than trying to do it here in writing, I think! No idea why they would find such a result inconclusive. Each Marker location shows 2 alleles.

They are saying that this looks to be due to a double mutation with my DNA. The DNA profiles on the test results consist of DNA markers (usually 15) that are used to determine if there is a biological match, the same codis markers used by the FBI for DNA evidence. Read more on this topic here https://goo.gl/2TxCwJ Not enough genetic markers were tested.

There are a range of presentations and possibilities for imaging findings. The extracted genetic markers from the DNA samples are represented in a table, listing each marker.
