Hehehe…Let’s rephrase:
Just because a marker for a gene or genes aliens have not been found yet doesn't mean they don’t exist.
Since the level of the gay population as a percentage of the heterosexual appears to remain rather constant, this also speaks to a particular gene frequency.
Oh? Then there’s a gene for chess players and swimmers since they are a “rather constant” percentage of the population. Is there a genetic aspect to all behaviors, or just this one in particular? This is just more goofy theory and junk science applications. You cite one conclusive genetic marker capable of replication 100% of the time and we’ll talk, till then your theory is just hopeful justification for your perceived injustice.
Many people with violent tendencies have a mutation in the gene that codes for the MAO-A enzyme. People with this mutation are much more likely to engage in dangerous, agreesive, and antisocial behavior.
MAO A is attributed to predict Parkinson’s and Alzheimer’s and a host of other REAL disorders. Your assertion has only been consistent when related to abuse and yet there’s still no replicable research that proves it anything more that circumstantial. Low levels of MAO A do not predict antisocial outcomes period!!! Funny thing though, if that were proven it would prove homosexuality the disease that it is…
I'm sure most of this is lost on an intellectual light-weight such as yourself. Take a deep breath, wipe the spittle from you screen, take the short-bus back to wherever you came from, and once again check your info before you post.
