Yeah there's actually an interesting study on this suggesting that the human race actively seeks out diversity, suggesting someone more genetically different from you is more attractive. It's interesting stuff.
Not just the human race. Though animals breed with their relatives, mammals especially primates actually prefer more those which are not closely related or not related at all (if there are alternatives). If they're only with relatives then you know.

Also, there's a study which suggest that people who share a large portion of their DNA tend to be attracted with one another. That's why there are many stories of couples who are unknowingly siblings maybe adopted or separated from birth or half siblings. It's growing up together or knowing that disrupts this attraction
