In the depate of nature versus nurture, a recently discovered gene has added contributed to the debate. A mutation to the MAOA gene, or the "Warrior Gene", is linked to anger management issues and violent behavior. When the MAOA gene is shortened, it inhibits the body's ability to clear excess seratonin in the neural synapses of the brain. This excess seratonin causes a good mood to turn agressive, pretty quickly. Research about this gene and the symptoms is relatively new. A team of scientists took genetic samples from a wide range of participants; ranging from buddhist monks to violent gang members. The genetic samples were tested for the Warrior Gene which some think is nature's cause of human violence. The results of the genetic tests showed that the three sampled buddhist monks had the gene, while other more violent participants did not. This result argues for nurture's cause of human violence, that a person's surroundings and upbringing are more perswasive in personality and behavior. Although some results were shocking, overall this research still leaves the debate of nature versus nurture up for debate.

small mistakes
I spot a few spelling mistakes including "In the debate of..." and "clear excess serotonin". Also, when talking about religion (or of the like), don't forget to capitalize them, like Buddhism. I'd also prefer if the acronym MAOA was spelt out, and then later reused in the acronym-form after showing what it means.
punctuation
In the sentence "A team of scientists took genetic samples from a wide range of participants; ranging from buddhist monks to violent gang members" the semicolor should be replaced with a comma. A semicolon is used to link to independed sentences that are realted in idea. "Ranging from buddist to violent gang members" cannot stand alone a sentence therefore a comma would be the better connection of the dependent clause.
abbreviation
Type out what the abbreviation means when first using it.
