What is the MAOA gene and how is it linked to violence?

This week we learned about the study of genetics. Genetics is the study of inheritance, or how the traits we have in our DNA make their way to the next generation. Mendelian genetics is the simplest form, and understanding how those genes are inherited makes for easy learning. What becomes difficult is understanding inheritance as it relates to exceptions to Mendel’s rules, polygenic traits, and the age old argument of nature versus nurture. Just so we all know, it’s never one of the other! We are basically always influenced by BOTH our genetics (nature) and our upbringing and environment (nurture). To what degree is sometimes difficult to understand. In this discussion we will visit the idea of inheriting a propensity for violence, a very controversial subject.

For this discussion you must read the following article and watch the following film:

Horgan, J. (2011, April 6). Code rage: The Warrior Gene makes me mad! (Whether I have it or not). Scientific American. Retrieved from https://blogs.scientificamerican.com/cross-check/code-rage-the-warrior-gene-makes-me-mad-whether-i-have-it-or-not/ (Links to an external site.).
Day, P. (Director). (2010). Born to Rage? [Film]. From National Geographic Explorer. Retrieved from https://vimeo.com/24659039 (Links to an external site.).
Then answer the following questions:

What is the MAOA gene and how is it linked to violence?
What evidence does the film Born to Rage? provide in support of a genetic predisposition for violence?
What evidence does the article “Code rage: The ‘Warrior Gene’ makes me mad! (Whether I have it or not).” provide to negate a genetic predisposition for violence?
Based on all the evidence provided, do you believe that enough evidence has been presented to suggest that violence is genetic?
Would you support the genetically engineered removal of MAOA variant linked to violence? What might the consequences of this be?

Once you have finished your posting it, publish it and then respond to two peer’s initial responses who disagreed with you. Did their arguments persuade you in the opposite direction? If not, how can you persuade them to your side? Be sure to be respectful and use examples that are supported in research.
