Then how can you explain no correlation before the daughter has become a teenager? If I understood you correctly, you suggest that parents of daughters divorce more often because the daughter was born to a couple of stressed parents (which is more likely to happen than a boy born to that family). If that would be the only cause of the divorce (I'm oversimplyfying, of course), then there would be no difference whether the daughter is a teenager or not. Perhaps parents think of taking care of a child in their first years of life as a moral obligation, which would reduce the divorce rate. However, it's still suspicious that the divorce occurs around the time the daughter reaches puberty, not some time earlier (after she's 5 or something).

I don't. I was specifically responding to yellowbeard's comment, which read:

> Childless parents as a result of self aborting male fetuses would not show up in the study.

Yellowbeard provided one explanation for the fact that, despite male fetuses being more likely to self-abort, there is no difference between divorce stats of young male and female children. My response said why that explanation was wrong. I wasn't saying that the self-abortion delta affects divorce ratios, only that it might.

(Indeed, I do expect that it does have an effect, but that that effect is miniscule and unlikely to be measurable.)
