The one all of our biology/genetics teachers like to use is sickle cell. A carrier of sickle cell (passive trait like blue eyes. You have to have bl bl to get blue eyes. bl Br will show brown eyes even though you are recessive b for blue eyes) can survive malaria because of the shape of the blood cell is slightly irregular, while full sickle cell adults die (blood cell too irregular to bond oxygen..IIRC) and full non-sickle cell adults get malaria and die. Sickle cell is passed on. However, white folks don't have it because we were freezing our asses off far away from malaria.

Yeah, I remember talking about sickle cell in biology when talking about evolution. I remember the pictures of the little half-moon-shaped blood cells.
