Criminal Genes?

Can genes predispose a person to crime? Some American lawyers are now using such a “genetic defense” as mitigation for convicted murderers. Are there genes for alcoholism? Or genes that make you gay, religious, prone to divorce, or even genes that determine how you vote? If you believe the claims of some of the scientists who call themselves “behavior geneticists”, many aspects of human behavior are in some way laid down by our genes.
