Genes don’t tell you about someone’s nutrition and fitness level, and it especially won’t tell you about the things most people value in a partner like their personality, values, sense of humor, etc. Even someone looking for a one-time hookup is usually going to be looking for at least a few of those characteristics if for no reason other than building trust that they’ll enjoy the experience. There’s one known factor which genes can tell you (MHC complex compatibility) but studies have been mixed on that and researchers have found fewer matches in married couples than a simplistic theory would suggest: https://en.wikipedia.org/wiki/Major_histocompatibility_complex_and_sexual_selection https://en.wikipedia.org/wiki/Major_histocompatibility_compl... Again, my point is simply that humans are not field mice. Our flexible brains are what make us human and you’re not going to be successful trying to build any model which doesn’t assume that.
