Are there any defining physical characteristics that can be positivly associated with the various Haplo Groups?

There might be some physical characteristics that are defined by certain Y groups, things like male fertility or maybe a tendancy to produce more male offspring than female offspring. There might even be some sex linked differences that are responsible for certain behavioral traits. I seem to recall a studyof a group of Dutch families had a tendency for males to be more violent than other groups. I don't know if this was linked to their Y chromesome or not but since it only seemed to be shown in the males I would assume that it did.
It's a little more complicated I suppose. Alopecia and colour blindness effects women too but to lesser degree. Go figure.
Interesting so I suppose the mdna points to more definable traits?
Possibly so.There are studies that have shown a positive correlation between the Y Chromosome and height, however they did not identify which Y DNA Haplogroup the SNP belonged to. That said, the countries with the tallest men in the world are also the countries with the highest percentages of men carrying Y DNA I1 and I2.
Surprisingly male pattern boldness comes from mother side, therefore Y chromosome is out of equation.Another thing I strongly believe would be influenced by the Y Chromosome is male pattern baldness and hair in general,
