So there you have it - yes, or maybe no 
Genetic factors can, just like social factors, influence the choice of mate.
When it comes to picking sexual partners, genes also have their role. Studies show that we innately find people beautiful who have highly symmetrical features and clear skin. It makes sense for the genes to tweak our hormones when we see a potential mate like this. Such a person is likely to be healthy and parasite free.
