Chimera Twins Story
skelley writes "Below is an audio link on this morning's story on NPR about Chimera twins, or people with two sets of DNA.
It turns out that every once in a while a set of fraternal twin eggs merge into one embryo. The resulting person has two sets of DNA.
The story says it is possible for a Chimera to have different sets of DNA in different body parts. This can cause complication for body identification, DNA typing for organ transplants, crime investigation, etc.
Researchers have no idea how common this is, but suppose that it is a reasonable percentage of all fraternal twin pregnancies, which would mean millions worldwide.

What have you got against NPR? This is cruel and unusual punishment for any web server.

Don't get me wrong I like dogs as well. YOu need to get to know a cat (not all of them but usally) before it is affectionate. Then it will be your best mate. Dogs are instantly your best mate. Cats are definately smarter (not mine, it still hasn't worked out glass doors).

Something along the lines of "cats, although they are more advanced upstairs, they are so independant they dont give a crap about you, theyll just find a home elsewhere, they're elite animals indeed, dogs, while less advanced, are loyal and dependant of their owner/master, some people suppose that dog people need the assurance a dog supposedly gives you, being the "emotionally shallow" animal the dog, supposedly, is."
When Focker (Stiller) claims that he's more of a dog-person, a disgruntled Jack (DeNiro) asks, "So you prefer an emotionally shallow animal, do you?"
MORTAR COMBAT!
Using DNA to test for a positive match is a sham. The National Research Council have admitted that much (remember the New York Times controversy when NRC released their report on DNA profiling in investigative work?)
After heavy pressure from various law enforcement agencies, they revised their report to say that it might be appropriate if the labs doing the tests were under strict national quality assurance (which they still aren't).
There have been several cases where a positive DNA match later turned out to indicate nothing more than that a person belonged to a certain group of the population. And there have been convictions that have been revoked because of this.
But imagine what would happen if the NRC published their original report? Thousands of convicts would want their cases retrialed. So that isn't going to happen. And dna profiling continues to be court admissable evidence.
For a good book on the topic, look for "Biologhy as Ideology: The Doctrine Of DNA" by Richard C. Lewontin, professor of biology at Harvard University.
Btw, did you know that the US is one of the few countries in the world where a lie detector test is court admissable?
