Hey criminals! Here’s how you get out of taking full responsibility for your dastardly actions:
Pretend your DNA sampleBlame it on your identical twin See if you have got the genes that predispose you to whatever crime you’ve committed
Murderer Abdelmalek Bayout and his attorneys selected possibility three. Bayout admitted in 2007 to stabbing and killing Walter Felipe Novoa Perez in Italy. During the first sentencing, he was found to be mentally ill. This year, neuroscientists additionally found abnormalities in brain-imaging scans and five genes linked to violent behavior, including MAOA.
Although there have been numerous cases since 1994 in which the defense argued for leniency based on MAOA deficiency, this is often the first case in that this tactic has been successful. Based on the scans and genetic testing results, the decide reduced Bayout’s sentence by another year.
Not everyone agrees with the choose’s decision.
"We have a tendency to don’t know how the whole genome functions and therefore the [possible] protective effects of other genes," says Giuseppe Novelli, a forensic scientist and geneticist at the University Tor Vergata in Rome. Tests for single genes such as MAOA are "useless and expensive", he adds.
Even worse, this verdict might open the floodgates to claims of all sorts the more we have a tendency to know about genetic influences on behavior. That list on top of is just regarding to induce longer.

Image: “Structural (left) and practical (right) MRI scan knowledge shows that subjects with the violence-connected version of the MAO-A gene (MAOA-L) had reduced volume and activity of the anterior cingulate cortex (blue area in front part of brain at left and corresponding yellow space in at right), that is considered the hub of a circuit responsible for regulating impulsive aggression. The color-coded areas show where subjects with the L gene kind differed from subjects with the H gene type.”
