Genetic Inheritance & Brain Psychology

The last year I studied biology was in my associate degree. I learned about DNA and RNA in details. I also learned about gene. It was so exciting to learn about those tiny tots determining our physical and mental characters. I used to think about genes as the “god’s own signature” to generations. It carries all the encoded informations from one generation to the other generation. The informations carried to the next generation can be good and bad. It makes somebody more intelligent compared to others.

I learned about mutation in one of the classes. According to Charles Darwin (1859) in a struggle fro existence, organisms that are perfectly adapt to their environments will survive unchanged. If the conditions are not favorable then the organisms will not adopt their environment perfectly, but a change in the structure of their gene will happen. A small change, mistake in one of the base of a DNA can change the properties of that and create sever problems. The mutation is responsible for the diversity in the world. Some times mutation helps the organisms to survive and some time causes problems.

Human went through several mutations and each of us differs from one another. Our abilities, physical characters, and mental characters are different. All related to the genes we own. Somebody can draw pictures, sing songs, lead a group, and the list goes on. All these are qualities and capabilities coming from the gene.

Genes are very much responsible for human intelligence, motor learning capabilities, criminality, alcoholism, and a broad range of other behaviors.

Even though research is progressing to alter the gene characteristics artificially, there are no known effective and safe techniques.
