Interesting you mention that. Because indeed some of the genetics researchers have attempted to identify certain alleles that might lead result in a propensity to violence, or even poor impulse control.
Whether their hypothesis has any merit or not isn't for me to say. But it serves nexus for the eugenics argument, that certain genes must be removed from the gene pool. And the eugenicists love their abortion.
Um. Half of the human population has some genetic information (otherwise known as a Y chromosome) that makes them a lot more likely to end up in prison. Crime genes exist.
