Why is gender ratio at birth 105 boys:100 girls

[river_flow]

Despite the fact that there are equal number of X:Y chromosome sperms , why do more boys are born compared to girl ? Any scientific reason for this ?

 

[epillepsy]

Y chromosome sperms are faster because they had less genetic weight to carry.

Men are high risk high reward (multiple impregnations if you get a chad son)

Women are low risk low reward (one impregnation every year)

Some people think that the gender ratio changes depending on the country

If it's rich you usually get more boys and if it's a shithole you get more girls.

More boys die in infancy so it balances out.
