Most parents will seek any reasonable advantage for their offspring. So come the day when we can see in advance that little Timmy will have violent criminal procilvities, or little Suzie will lean towards lesbianism, I rather expect that parents will correct any and all genetic variations that will make life more difficult for their Timmy and Suzie.

The fact of the matter is that being gay is a lot of hassle and trouble. No loving parent would wish it on their child, and if there were and easy gene fix, I'm sure it would be applied more often than not.

Here's a ponderer -- what if we find out that violent and criminal behavior has a genetic origin? What will that do to our criminal justice system? If we become capable of "fixing" a rapist, should we still lock him up? Should it be for just as long as we would lock him up if he weren't capable of being fixed?

If broad personal behaviors turn out to have genetic origins, there will be a lot of questions raised that will have no easy answers.
