If it is genetic, it's more than likely a gene people can carry without actually exhibiting the trait e.g you can be a straight person who, although straight, carries "the gay gene". This is assuming such a gene exists.
This is what the recessive trait discussion was about in my post. If it is genetic and it is carried without exhibiting than it is known as a recessive trait associate with recessive genes. If it were a recessive gene we would observe two phenomena.
1. The exhibition of the recessive genes as a trait to a greater extent than 10% (approaching a limit of .
2. The recessive genes (and thus trait) would not be ubiquitous across numerous species or sub-groups, but will have statistical prevalence within a given species or sub-group and be non-existent in others.
Even in such a case determination of the whether the trait is beneficial or detrimental will still follow the genetic mutation model in terms of subsistence and propagation.
