[ZOOKER]

Article seems to imply that male (and only male) DNA is found in the pregnant mother's blood stream during pregnancy.

When you think about it, it makes sense.

The male DNA is to desensitize the mother's immune system so it won't attack the fetus in the womb.

There is no need for female DNA, it would be identical to the mother's, right?

I could so nail being a doctor, it's so easy...

[Verginius Rufus]

Half of the nuclear DNA of any child comes from the father, so a female embryo would seem to pose as much danger as a male embryo. (The mitochondrial DNA in the baby would be identical to the mother’s whether the baby was male or female.)
