Document Summary
We can distinguish three broad sets of factors that contribute to differences and similarities between people in personality: genetics, non-shared environment, shared environment. Shared environmental factors are those that are experienced in common with a number of people. They might include family environment, school environments, and broad-scale cultural conditions. Non-shared environmental factors include all those experiences which are unique to the individual, such as peer groups, differences in parental treatment, etc. It was found that non-shared environmental experience has the most influence on who we are. An individual"s genotype is the specific collection of genes that he or she inherited from parents. A person"s phenotype is the totality of his or her visible or measurable characteristics. Our interest is in the relationship of the genotype to the phenotype We want to compare phenotypic personality in individuals who differ or are similar in genotypic personality.
