    chimeras - WHAT IF DNA IS WRONG?

    I watched this highly unusual documentary about a month ago and found it very interesting.

    A woman who DID GIVE BIRTH TO HER CHILDREN - almost had them taken away because DNA testing PROVED THEY WEREN'T HERS. The LE thought her boyfriend and her were hiding something "sinister".... then she found out about another woman across the states that had the same problem....

    CHIMERA'S ARE FUSED TWINS.... where one baby is born seemingly healthy, often with NO anomolies or strange issues. These chimera children have 2 SETS OF DNA - the twins are NOT identical... but fraternal.

    Now think about the consequences. Some scientists believe that this Chimera rate could be as high as 30 people per 1000 of "normal" twins birth rate. It took scientists quite sometime to determine that the above lady INDEED had two sets of DNA within her body.... they had to test various tissues in her body to determine this.

    SO MY QUESTION OR CONCERN HERE IS THIS: WHAT IF??? there are people with this Chimera anomaly that have been either A: wrongly convicted or B: got away with bloody murder.

    This is most interesting to me. I have heard of cases where men had one DNA result from blood tests and a different result from their sperm. This could explain it.

    Maybe this should be looked at much more closely than it has been as far as using DNA to rule someone in or out for a crime.

    I saw that episode. One thing that confuses me- don't identical twins have identical DNA? So it must be fraternal twins where one dies before birth?
    Just when I think that I have seen the most depraved things a human can do to another human, somebody posts a new story...........

    Why is it that when a custodial parent fails to provide for a child it is called neglect and is a criminal matter. But when a non custodial parent fails to provide it is called failure to support and is a civil matter?

    I found there are two related terms- Mosaicism and chimerism.

    A similiar story to what you had heard.

    It is on fraternal twins where the ONE BABY BORN has both DNA.... because that child very early on "swallowed" the fraternal twin (fused, morphed, whatever) and they became one person. and only one baby is born with the fraternal twin within itself. Often Chimeras only have a trace of the other person's DNA within it's system and once in awhile, it is born with both sexes (hermaphrodite). There was one baby on the documentary where literally as if someone drew a line straight down the middle of the child. One half was light coloured black baby and the other was of a darker black child. One half had female genitals and the other had a partial penis & scrotum. As Kramer on Seinfeld said "God is a maaaaaaaaaaaaaaaaaaadddddddddddd scientist".

    Sounds so weird.

    BTW, didn't know CSI did a show on this, I'll have to watch for the rerun.
