AI Thread Summary
The discussion revolves around the genetic testing results of a family, raising questions about the paternity of two children based on their chromosome patterns. The mother has a genotype of 17,21, the father 19,20, while the daughter shows 19,21 and the son 17,19. This raises concerns about whether both children could be from the same father, as the Y chromosome should be identifiable through the mother's results. The poster notes that similar discrepancies have appeared in other cases, prompting inquiries into the validity of the results. There are suggestions that the results might be inaccurate or even fabricated, and a recommendation is made for the family to seek testing from a different laboratory for confirmation. The discussion highlights the complexities of interpreting genetic data and the importance of consulting professionals for accurate assessments.

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?
