“Whole lot of girls with older parents it seems.”
That’s an interesting observation. Are you aware of any data on that?
- jleyank 3y agoIt’s anecdotal but based on 20-30 years observations. Recall reading something about the Y chromosome being more fragile so age and lab work would agree with this. Just knew lots of 40-ish coworkers and buddies with lots of girls and few boys.
- red-iron-pine 3y agoCan't speak to age, but there is a well known phenomenon that fighter pilots only have girls. What data there is backs that up, too. https://www.upi.com/Archives/1987/12/01/Air-Force-fliers-really-do-have-more-daughters/1667565333200/ https://www.upi.com/Archives/1987/12/01/Air-Force-fliers-rea... Wouldn't surprise me if similar factors, e.g. stress on the body via aging, also impact the Y chrom and lead to more girls.
