If you're male, have a good look at your father. Hopefully not surprisingly, you'll notice some resemblance. If you don't, get a picture from your father when he was your age.
Maybe a little more surprising are the findings reported in a nice little paper in Current Biology (MSNBC news report). Biologists from the University of Exeter in the UK have looked at how another trait is inherited by sons from their fathers: their success with females. And because the fruit fly Drosophila is such a great model for heredty, thats the system they studied. In the fruit fly, the female can prevent forceful mating from the male. It is the time it takes for a male to copulate with a female after courtship has started which can serve as a measure for attractiveness in male Drosophila. The researchers found that the time it takes males flies to copulate is highly correlated with the time it takes their sons to copulate, indicating that the sons inherited the attractiveness of their fathers.
What I found most interesting about this study, though, is that it contradicts earlier experiments in a closely related fruit fly species. The researchers here had used D. simulans for their experiments, while previous work using D. melanogaster failed to reveal such a heritabilty of attractiveness. On the contrary, this paper found that male fitness (which does not equal attractiveness, but I'd assume the two to be correlated) is not inherited by sons.
