personality disorders and how they are affected by genes
Researchers are currently looking for a link between people’s personality traits and their genes. ... Previous research on animals and humans has shown that there are links between certain neurotransmitters and personality traits and though our genes direct our physical development, their effects on our behaviour are primarily indirect (Mann 1994). Factors such as genes direct our personality, while other factors, such as the environment also form the individual. Genes, however, influence physiological factors such as particular behaviours and thus make people more apt to possess specific behaviours such as depression. Although the search for genes that explain our personalities is currently thriving, it carries with it many moral issues and will have both positive and negative implications both to society and to oneself.
