I'm sure there are some details of cultures that are somewhat genetically defined like terms of desirable appearance. It kind of has to fit in a frame with the genetic factors that matter for appearance. An example would be the desire to be pale in some Asian countries. With their genetics it would show if they've been working out in the sun because they'd tan, or if they're wealthy and don't have to work in the sun because they'd be pale. This kind of factor is nonexistent for a people whose genetics do not allow a noticeable difference in appearance from being out in the sun.
Another, in Asia again, is the standard on what is "fat." The principal of my old school summed it up for me nicely. He went to Taiwan, and there, apparently the girls really dig white guys. So he (the principal) asked a Taiwanese guy he knew "why don't you guys appear threatened by the white guys that come to Taiwan? Aren't you scared they'll get all the girls and you won't?" The guy replied "they take all the fat ones." American guys like some curves, which tends to mean a little meat on the bones. Asians, however, think of that as fat, because (I'm pretty sure) their genetics tend to make them skinny, thus changing the position of the bar separating "fat" and "skinny."
However, these genetic factors are far from defining the entire cultures.
