It was the frequency of twins in my immediate family that began my studies on this subject.

We have three sets of twins i. My daughter, identical girls. My younger brother, faternal boys. My elder brother, his daughter, another set of faternal boys.  

Science tells us about the multible combinations of the overwhelming variety of possible combinations of the twinning possibilities. As i studied.

Now we have arrived in a place where we also know of the disappearing twin. Concluding another factor in the very complex determination on our chemical compound of varients.

Signs of this distinction can be seen in two different eye colors. Or not seen at all. It may shock you to realize these combinations can include body parts of both female and male organs in one making determining even the very sex of the newborn child impossible!

Yes, these conceptions are remarkable.

In our human nature ,to find these realities , impossible to understand without the evidence before our very eyes dismissed.

The efforts of distressed families to hide these abnormalities have hindered us from such truths.

For me to quote every source of my own studies and sources would be exhausting. Instead, this is not my purpose. I provoke you to research yourself. My purpose is to ask the question, how DNA from the mouth can be accurate concluded to be a reliable indicator.

Someone who's a chimera still gets all their DNA from their parents; it's just that different parts of their body carry different subsets of the parental DNA. While I've heard of the cases where an initial DNA test showed that someone wasn't the parent of their child, I haven't heard of any cases where the DNA showed that the parent was unrelated; I'd expect the parent to test as an aunt/uncle of their child in that case, and that the child's grandparent would still test as their grandparent.

If I were managing the tests for such a person? I don't know whether the genenealogical DNA tests that use cheek scrapings collect different tissues from the ones that use saliva, but if they did and the person with chimera DNA had different results from different companies, I'd upload both into GEDmatch.

. MODERN DAY HUMAN CHIMERAS

With the growing realization that natural chimeric humans are more common than originally thought, the consequences have only begun taking shape. Every aspect of law that relies on the validity of DNA may be affected. The first case study involving modern day human chimeras includes two mothers that had their lives changed forever when a DNA test proffered the impossible: their own children were not genetically related to her. 

You can rely on one test because a person who is a chimera is made up of fertilized eggs which have become fused and those fertilized eggs have the same parents.

A paternity test for a child born to a chimera might show the "mother is not the mother" but a paternity test is not the same type of DNA test as that used for genealogy.  The amount of shared auDNA might look like that of an aunt to a niece or nephew.
So this is a different  DNA test? I m confused!

I still can appreciate the merit behind the test for DNA, I would only pause to say having both the DNA test as well documentation births deaths etc. would be necessary for true accuracy. I would never want our results to not be supported by data.

A paternity test is different from each of the four types of DNA tests usually used for genealogy.
