What a ridiculous and offensive suggestion, widespread genetic discrimination. You don't have to be a scientist to understand why that's bad. Even if (or precisely if) some skills and proclivities are mostly inherited, that should not prevent people that managed to overcome their native shortcomings to find a fair place in society according to their actual, developed skills.
We already know for a fact that males are more aggressive, females have lower orientation skills and Asian kids are less agitated. The genetic markers are so strong there you can read them on the person's face, yet, discrimination on any of those gender or race characteristics should be repulsive to anyone.
