Document Summary
Chapter #3 part 1 biology and behavior. *individuals differ from one another by only about 1 to 1. 5% of their genes* Later it was realized that eminent men and their families had less to do w/ genetics rather than economic well- being, social status, education & other advantages. Mzt = monozygotic twins reared together: family studies of intelligence, as twins get older, degree of variance in iq accounted for by their genetic similarity increases (genetic. Heritability: statistical estimate of the proportion of how of a measured variance on a trait among individuals in a given population is attributable to genetic differences among those individuals. Limitations: only apply to populations, not individuals, only apply to particular group living @ particular time, can differ for groups of people who grow up in different environments, high heritability immutability. Effects are cumulative (a combination of genes is required to render a heritable trait!)
