If you are a geneticist, how do you factor in people who aren’t XX or XY?
I’m not a geneticist, although I have studied both genetics and biometrics at the majors-level in University. I’m a statistician, and good statisticians eliminate outliers from their analysis. Ergo, the existence of minuscule variations on the XX/XY paradigm do not affect the fact that humans are a sexually dimorphic species. There is no “third sex” out there running about in any significant way.
Also, how do you account for hormone differences that unborn babies are exposed to?
I can think of about three or four issues you might be referring to, but I’d prefer not to guess. What’s the context for the question?
