Behavioral geneticist focusing on the genetic contributions of behavior employ a variety of methods and techniques to determine the level of which psychological characteristics and traits fluctuate due to genetic factors. Behavioral geneticists utilize evidence collected from environmental effects on personality. One popular technique used to determine individual differences in personality includes twin studies. Twin studies are a vitally important tool for dissecting the nature versus nurture argument. Twins provide a naturally occurring experiment and they are most likely the best indicator of determining whether biology effects traits and psychopathology in human beings. Researchers are seeking circumstances involving twins providing evidence of known variations in the extent of genetic similarity or environmental stability. The key factor in utilizing twin studies to determine biological basis for personality differences exist among identical twins and fraternal twins. These studies provide data among the individuals that are genetically identical but yet, display visible differences that may be attributed to environmental differences. Additionally, researchers used such studies involving …show more content…

Researchers have identified molecular genetic factors among individuals that makes them more or less prone to experiencing a variety of emotions. Genetic factors were studies that influences certain chemicals in the brain including Serotonin and Dopamine. Researchers focused on genes that had adverse effects of Serotonin and Dopamine. Researchers contend that variations in the gene level have significant effects of chemical levels in the brain and those fluctuations in genetic backgrounds were attributed to environmental experiences of the
