This possible phenomenon was discussed in many threads, as an explanation to why some Y haplogroups became so dominant. Maciamo's hypothesis about dominance of R1b clades in Western Europe is based on it too. This hypothesis states that males of certain haplogroups, like R1b, or some of its successful clades, can father more sons than daughters. More than other male haplogroups. This way after many generations, this little advantage, in increased number of sons, can grow R1b haplogroup to superior level in population. For example in Ireland and Basque.
It'll be some time till we have true scientific research done in this regard, however there might be a shortcut. We have available statistics of kids sex at birth per country. In Europe more boys are born than girls. Per 100 girls there is 104 to 107 boys born. It seems to be a natural ratio, with exceptions being Albania and Kosovo at 112, and Georgia and rest of Caucasus at 118 boy to girls. These exceptions might be due to selective aborting, a cultural aspect of boys preference. No wonder bride kidnaping is popular there. But I digress.
I prepared a little map how it goes for Europe. What do you think? Is there something to keep this hypothesis alive, and not only for R1b?
The darker the colour the higher the ratio for boys.
