Document Summary
Behavioral genetics: inheritance of our behavioral traits. Traits tend to be influenced by many genes. The hereditary passing on of traits determined by a single gene (huntington"s, tuberous. When many genes interact to create a single characteristic (height, skin color, hair, eye color) Complex connections between genes and behavior and environment. Specific genes can cause specific diseases but play only a small part in creating a given behavior. Environmental events can interact with genes to make behaviors more or less likely (i. e. stress) The expression of certain genetic traits can still be influenced by the environment. Teasing apart and identifying genetic and environmental influence on behavior requires special techniques. Heritability refers to the extent to which a characteristic is influenced by genetics. The study of hereditary influences on twins, both identical and fraternal, who were raised together and apart. Studies hereditary influences by comparing genetic markers (specific parts of the human genome)
