Document Summary
Help researchers study the impact of genetic vs environmental influences. Monozygotic twins raised together vs raised apart. Some evidence that those raised together may be less similar than those raised apart. Impossible to separate genetic influences from environmental influences. Can work together to determine human behavior. Epigenetics changes in gene expression that are due to non-genetic (epi = outer) influences. Study: role of genotype in the cycle of violence in maltreated children. Type of mao-a gene lower vs higher levels of mao ( nature ) Convicted of violent crime by age 26. Result low-mao gene + maltreatment increased probability of being a violent criminal. Heredity: genetic transmission of characteristics from parents to offspring. Heritability coefficient: how much of the variation seen in a certain trait within a population can be attributed to genetic variation, as opposed to the environment.
