I don't think you understand how genes work. No one gene can predict one person's abilities.
Also, environment, personal experiences, education can play a huge factor, possibly an even bigger factor that genetics.
As for the "shallow" part, that has nothing to do with science or how we understand genetics. You may not then see the irony in using this colloquialism, in claiming someone comes from the shallow end from the gene pool, but I certainly see it from my point off view. I suggest next time you make a smart ass comment about genes you should probably do some reading on the subject matter.
Are you trying to convince yourself that you are smart? No one gives a $hit what you studied mate this is bigfooty.
