It's an interesting observation, makes me wonder if it's ability to travel, or actually reproduction like you say. Probably a bit of bohth. Devil's advocate might say it's more likely girls that look like that will travel, or even that more girls who look like that are around in other parts of world due to chaos in parts of Europe lol

This observation was purely physical. A lot of Russians of course have different genotypes and many are mixed. But there is a bigger concentration of Russians that look like me. And we can quickly point each other out in other countries when we travel.
