The general consensus has been that Y-chromosomal DNA only contains a few of genes relating to male fertility and does not influence the carrier's appearance, except of course for the male characteristics influenced by testosterone. I have argued before that some Y-chromosomal mutations, in the coding region, certainly play a role in male behaviour and sexual selection, considering that such mutations typically define major haplogroups or subclades. The more I compare the looks of people whose Y-DNA haplogroup I know, the more I feel like people belonging to the same haplogroup do often (but it's not always that clear) share some common looks.
I just learned today that Ben Affleck belongs to J2a1-M319, a subclade found mainly Greece and Italy, but especially in Crete. It could have been spread by the Romans to western Europe. Ben Affleck has mixed Scottish, English, Irish, German, and Swiss ancestry. Regardless of his ancestry, there is something that looks quite J2 about him.
Here are some other known J2 people. I would say that they all share a certain relatively gentle boyish look and have a face that is rather oval. These three are all Jewish, but they are very different in type from say Woody Allen or Albert Einstein.
Mike Nichols
Burt Bacharach
Matt Lauer
Another example is Swedish actor Max von Sydow, who I recently learned belongs to a Pomeranian subclade of R1a. There is only about 19% of R1a in Sweden, yet his looks screams R1a. He know a Polish guy who looks just like him.
Von Sydow has German ancestry, although that does not justify his Polish looks. Let's take two pure Swedish actors, Stellen Skarsgård and his son Gustaf. I do not know their haplogroups, but I would bet that they are R1a too. I can't explain it with words. It's just something in their expression.
Stellen Skarsgård
Gustaf Skarsgård
