Up until recently...within my lifetime...when one person had the DNA of the opposite sex within them, it was due to that person having been a twin. You see, a fraternal twin which absorbs the other twin, now has the DNA of the opposite sex within him or her.
Flash forward to the present...Many unsuspecting pregnant mothers who were exposed to rubella during pregnancy were convinced to abort their babies through fear. Amazingly, only about 2 out of 80 babies sacrificed had contracted rubella. (Perhaps the other 78 mothers had awesome natural immunity due to being happy, etc. Never let anyone convince you to sacrifice your children.) Anyway, thanks to the boy's DNA and girl's DNA being in 3 shots that people routinely put into their kids, we have rampant infertility and gender confusion. Yes, glyophosphate and some other pesticides are altering humans, but did you know what vaccines are doing to them? Listen to Maricella and read Wise Geek's information on Chimerism if you want to know more.

Vaccines can cause auto=immune diseases, too. Vaccines may cause microchimerism as well.
