Ummm so how does one fail such a test

Nahhhhhh.......this can't be true? Wow.

That is weird and yes, good question...how?

This one may be way out there, and I can't remember the name. But there is a medical condition where in-utero there were twins, fraternal twins not identical twins. The embryos merged, becoming one person (just the opposite of cojoined, where identical twins didn't completely split - becoming two). Then there were two separate people who became one. Really screws up DNA tests because you are carrying the genetic makeup of two entirely different people. One test will show up as you...the other as your brother (the one you don't have because only one of you was born). In fact, if you have this - when they test you and your child - your child will show up as not yours.

If you are a man and it happens, you get pissed off. If you are a woman who carried that child for 40 weeks...you get really confused.

No, I don't make this sh*t up, I just read too much. This may not be the case at all. Maybe she just visited Dr. Will Cuchapekeroff and went from a he to a she.

I think I caught a CSI espisode that had something like this going on.

I missed that one. I've only seen CSI like 3 times. It's really weird though. I saw it in a real court case where a woman was being charged with fraud for claiming children that weren't really hers for taxes or welfare or something like that. DNA tests couldn't prove that they were hers, only the fact that she carried them for 40 weeks and the doc that delivered them said, "yeah, I saw them come out of her and have cared for them for their whole lives."

The scientific evidence was pretty complicated, then what her actual situation was came out...really interesting stuff.

Isn't there also some condition (can't remember what it's called) where you don't have testosterone receptors (or maybe it's androgen receptors) so you're genetically male, XY, but develop as a female?

You sure you didn't make that up Welch???

These are called hermaphrodites, meaning the person has ambiguous genitalia, and could not be identified by the people who examined the child at birth as either a male or a female.

Well, I've only seen it on TV, but I think it's real. I majored in Biology, I really should know if this exists or not.

Sucks to be him, doesn't it? Not only did he not get the gold, but he got beat by a woman too!

No, that's not the one I'm thinking of. The one I'm thinking of is where there were actually two embryos that merged to become one person with two different sets of DNA. Hermaphrodites aren't THAT uncommon, these folks are pretty rare.

Then you must mean this Welch.

Chimera, a mixture of two individuals - non-identical twins - who fused in the womb and grew into a single body.

An analogy is two jigsaw puzzles cut using an identical cutter, but with different pictures. A single puzzle can be made out of the mis-matched parts, but the completed puzzle will show parts of both different pictures. The likelihood of a child being a chimera is increased if the child is created via in vitro fertilization. Chimeras can often breed, but the fertility and type of offspring depends on which cell line gave rise to the ovaries or testes.
