Double Helix

Most of the story is interesting. But, when the teacher tells the students that they must all disrobe in front of each other, all logic is tossed out the window. The reason the teacher gives is that he has to know if anyone has a tattoo, birthmark, surgery or other marks that will disqualify anyone from his study. Logic would say, "If you must know, then let each of us do it privately." As one of his students, I would have decided the teacher is a sexual pervert (especially since the woman he chose are sexy).
