I am not sure your approach to garner interest in your discussions when phrased in this manner is going to make people anxious to answer you at all. Your question here is written in a somewhat offending manner. Do you know the answer to your question or are you really interested that someone can give it to you? I am not at all sure of what particular "gene" is responsible for love and affection but there most certainly is a hormone that is it is called oxytocin and is associated with the ability to maintain healthy interpersonal relationships and healthy psychological boundaries with other people. It is called the love and cuddle chemical.
