Fathers with some haplogroups of Y chromosome seem to have on average a higher proportion of boys among offspring:

But are these differences really significant?
If so then for example in Ireland or in Wales (where great majority of fathers are R1b) boys should significantly outnumber girls...
Is this the case - are boys more numerous among children there?
Any data on sex ratio among newborn babies available?

The haplogroup with the highest sperm count in the study was hg1, which unsurprisingly is R1b, followed by hg3 (R1a). This supports my hypothesis that R1a and R1b became dominant in Europe, in spite of their late Bronze-age arrival, thanks to a genetic predisposition to father more boys compared to other haplogroups. Indeed, a higher sperm count is one of the principal factors in raising the chances of having a boy rather than a girl.
