In summary, A person reviewed some results for someone and found it odd that multiple lines had the same issue. The results showed that the mother was 17,21, the father was 19,20, the daughter was 19,21, and the son was 17,19. The person is questioning if the children are from the same father and if the results could be fake or if there was a mutation in the chromosomes. They are seeking opinions from biologists and considering getting tested at a different lab.

Hello just reviewed some results for someone and thought it was quite odd.

Below I have included an example of what was explained to me.

Mother: 17,21
Father: 19,20
"daughter": 19,21
"Son": 17,19

By having the mother tested the "Y" chromosome should be capable of being determined.
The children are a boy and girl and being said to be both from the same father.

But with over 4 other lines within results with the exact same issue as above makes me want to ask opinions from biologists to explain if this is possible.

Are both the children from the same father? Are the kids even his?

I've read of mutating chromosomes due to smoking ect. Doesn't fit with above result.

Are theses faked results? Should they all get tested at alternate lab?

There's no way anyone can answer you because those numbers could mean anything, please consult the clinic that issued this information.
 

1. Can a paternity DNA test be wrong?

Yes, there is a very small chance that a paternity DNA test can be wrong. The accuracy of the test depends on the quality of the samples provided and the laboratory performing the analysis. However, modern DNA testing techniques have a very low error rate, making incorrect results extremely rare.

2. What are the possible odd findings in paternity DNA test results?

Some odd findings in paternity DNA test results may include unexpected or unexplained genetic matches, discrepancies between the reported relationship and the DNA results, or results that do not match the expected patterns of inheritance.

3. Can a paternity DNA test determine paternity if the father is deceased?

Yes, it is possible to determine paternity through a DNA test even if the father is deceased. However, the test may require additional samples from other family members, such as siblings or grandparents, to accurately determine paternity.

4. How long does it take to get paternity DNA test results?

The amount of time it takes to get paternity DNA test results can vary depending on the laboratory performing the analysis. Generally, results can be obtained within a few days to a few weeks.

5. Can a paternity DNA test be done without the father's knowledge?

Yes, a paternity DNA test can be done without the father's knowledge. However, it is important to note that it is illegal and unethical to obtain someone's DNA without their consent. It is always best to have all parties involved in the testing process and provide informed consent.
