Document Summary

Chapter 4: 133-173 (nature, nurture and human diversity) What makes you you: share genetic and behavioural similarities with family, these behaviours produce and protect offspring. Behavioural genetics: predicting individual differences: behavioural geneticists: stud differences of heredity and environment.
