shouldn’t there be decades worth of medical studies that captured whether the subject bore one or more male children? Perhaps a study of studies could yield some interesting information.
My ex-wife had 3 sons with her first husband. She liked hunting, fishing, high-performance cars and sports. Oh, and Tom Clancy books.
Not bad for a girl from Colorado. :)
Not sure that screening for male children vs. female children would necessarily reveal anything. The article said they found fetal DNA that could have only come from a male - i.e. the XY chromosome. Finding a female child’s fetal DNA in the mother would be much harder, since it will look the same (XX chromosome) under a microscope. They’d have to sequence the mother’s and daughter’s DNA to compare. They just plucked the low-hanging fruit first. More likely that all children (male and female) donate DNA to the mother, which was unknown previously, and this can impact the mother’s health. Comparing women who have had vs. not had children, which has been done, reveals some statistical differences (occurrence of breast cancer for one, I think) in health prognosis, and this DNA chimerism may be part of the answer. Might also explain why both my wife and daughter seem to be getting more stubborn simultaneously...
But then again, I’m an engineer, so all of the above may just be a load of obama-spew...
