Our genes do have some relationship to our body odor, and smell does play a role in whom we're into.
One oft-cited study had heterosexual women sniff mens' shirts at different points during their menstrual cycles.
"We found we cannot anticipate how much individuals will uniquely desire each other in a speed-dating context with any meaningful level of accuracy," Joel said.
"I thought that out of more than 100 predictors, we would be able to predict at least some portion of the variance.
"Romantic desire may well be more like an earthquake, involving a dynamic and chaos-like process, than a chemical reaction involving the right combination of traits and preferences."

Valentine's Day is on the way, and whether you're paired up or not, it's only natural to ponder whether or not there's such a thing as "the one." It's time to forget the pickup lines and personality tests: Here's what science says makes us physically and emotionally attractive to others — and compatible with them as well. Before anything else can happen, you've got to have an "in." What is it that's going to catch someone else's attention? By looking at which faces we find the most attractive, researchers have found that our favorites tend to be symmetrical.

The researchers used data from two samples of speed daters, who filled out questionnaires about more than 100 traits and preferences and then met in a series of four-minute dates.
Oh, and those instant-attraction pheromones we're always hearing about? Although they do exist, they don't function the same way in humans as they do in other mammals. When we find someone physically attractive, we tend to find that person attractive in a lot of other ways, too.However, a recent study indicates that asymmetry isn't actually related to a likelihood of illness — knowledge that has led some people to disregard the previous idea that we seek out symmetry for its good health indications.Instead, research suggests there may be some correlation between symmetrical facial features and certain personality traits, such as extraversion and openness, that humans like.Afterward, the participants rated their interactions, indicating level of interest in and sexual attraction to each person they met.Joel and her colleagues used a cutting-edge machine learning algorithm to test whether it was possible to predict unique romantic desire based on participants' questionnaire responses and before the individuals met. They found it was possible to predict the overall tendency for someone to like and to be liked by others -- but not which two particular people were a match.When we're on the lookout for "the one," other genetic factors could come into play.For instance, we may favor partners with complimentary MHC genetics in order to beef up our offspring's immune systems.But, although there's an entire dating site based on this idea, there's not enough evidence to suggest we should be basing our relationships on genetic compatibility.And, even if these are some of our deciding relationship factors, they probably aren't the predominant ones.The bottom line is relationship science still has a long way to go to decipher romantic attraction and what makes two particular people click, said co-author Eastwick. "It may be that we never figure it out, that it is a property we can never get at because it is simply not predictable," Eastwick said.
