Monoamine Oxidase A (Warrior Gene)
Human behavior is complex and influenced by our genes, our environment, and our circumstances. Popular science and the media have dubbed one of the most provocative and often controversial of genetic variants as the “Warrior Gene.” Studies have linked the “Warrior Gene” to increased risk-taking and to retaliatory behavior. Men with the “Warrior Gene” are not necessarily more aggressive, but they are more likely to respond aggressively to perceived conflict.
Located on the X-chromosome, the MAOA gene is one of many genes that play a part in our behavioral responses. The “Warrior Gene” variant reduces function in the MAOA gene. Because men have one copy of the X-chromosome, a variant that reduces the function of this gene has more of an influence on them. Women, having two X-chromosomes, are more likely to have at least one normally functioning gene copy, and scientists have not studied variants in women as extensively.
With one X-chromosome, men with the “Warrior Gene” will show a value of 3. Other men will have normal variants: 3.5, 4, 4.5 or 5. With two X-chromosomes, women will have two results. For example, a woman might have 3 and 3, 3 and 5, or 4.5 and 5.
