Just because a technology can be misused does not make it invalid. Just because a technology is valid, does not mean it cannot be misused. The point that is pertinent here is the validity of genetic science. If it is invalid, then please account for CRISPR and knockout mice.

Chronology has been dismissed as junk science yet let's face it we can all look at some people and tell that they are retarded or a basket case or a mean person or a nice person. The problem is we will be right most of the time but not all of the time. Reading the genome is the same way. A certain number of people will have a marker or snip or whatever you want to call it at a certain place in their genome and tend to exhibit a certain trait but it's not guaranteed. It could be in 66% of all cases or perhaps in rare instances over 99% of the time but it will not always be 100% correct. I'm not saying DNA should be dismissed as junk science but then neither should chronology and I suspect even though it has been that it's probably because most of the worlds most powerful people are psychopaths and rather than be discovered have influenced science to dismiss chronology entirely. All that needs to happen is for DNA science to progress to the point that commonalities between psychopaths and leaders be discovered and understood by the general public and watch how fast DNA analysis goes away and becomes dismissed. Right now it is in it's infancy and not quite understood so many people will believe whatever they are told about it without understanding what is actually going on. In a way this is also junk science and could be used against us as in innocent assumptions that later on prove not to be correct or at least as correct as we are led to believe. There are primitive societies that believe in bone pointing because when a medicine man points a bone at someone they wish to get rid of they nearly always die, yet this rarely works in modern societies that don't believe in it. There is a real danger that people will start believing in DNA much like primitive societies believe in bone pointing and that instead of indicating traits they could actually be causing them due to the superstitious tendency of people to believe in things that they don't quite understand.
Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Examples of human polygenic inheritance are height, skin color, eye color and weight. Polygenes exist in other organisms, as well. Drosophila, for instance, display polygeny with traits such as wing morphology, bristle count (20170808 dead link) and many others.
