Genographic Chaos

The Genographic project tests your DNA and tells you something about your ancient genetic origins.

If you're a male, it tests the DNA of your Y-chromosome. This is passed straight down the male line of descent.

If you're a female, it tests the DNA of your mitochondria. This is passed straight down the female line of descent.

But somehow my brother-in-law's test came out wacky.

First, they gave him test results for his mitochondrial DNA. He was supposed to get the Y-chromosome test.

Next, his mitochondrial results don't even match those of my wife, who had the same mother he did.

It's a muck-up to make your toes curl.
Unless he was switched at birth and is really a girl.
