The data from the swab is then combined with personality traits from the user's social media profile. 5, reasons for biological compatibility edit, there are several biological reasons why women would be attracted to and mate with men with dissimilar HLA alleles: 6, their offspring would have a greater assortment of HLA alleles theoretically giving them a wider diversity of antigens present.

Your immune cells don't know a virus from a transplanted kidney; they work by distinguishing between "self" and "non-self".

Hes particularly dismissive of the concept of pheromone parties, calling them a fun and interesting way to break the ice in a potentially stressful social situation.
