So, we'll be getting an ultrasound at some point in the near future. In the meantime, there is one very commonly-asked question, which is:
"Do you know whether it's a boy or a girl yet?"
The standard, non-geeky answer is, of course, "No." But really, that's boring. And of course, despite the fact that ultrasounds don't happen until at least week 18, L.E.O.'s genitalia have already developed. They are simply unobserved.
In terms of gender, therefore, we are dealing with a quantum superposition of states. From the standpoint of an outside observer, the baby is both a boy and a girl. Or perhaps 50% male and 50% female. Technically, from this standpoint, that means it has 1.5 X chromosomes in each cell (and 0.5 Y chromosomes). Of course, from the point of view of an inside observer, i.e. L.E.O., the wave function has already collapsed.
Yeah, yeah, quantum physics doesn't really work like that on a macroscale, I know. Still, more fun than just "No."
