Reply to comment by Thin-Rip-3686 in TIL that the ratio of male births to female births is 51/49%, and it's thought the ratio of X and Y chromosomes in the man's sperm is most likely the cause. by iKickdaBass

I’m no science dude, but I would think a difference of a 2% spread could easily be accounted for by a 3% shift. 51 is only 4% larger than 49, and 2% larger than 50.

You forget the importance of percentage of overall mass. It’s probably more like the race performance difference of two identical cars, one with 3% more fuel in the tank, versus one with 3% more overall weight.

Little effects like this can produce outsized results or no change in results, but the “sized” result is way less than 2%.
