Document Summary

Chromosomes made up of dna store and transmit genetic info. Genes, containing segments of dna are units of hereditary info. The percent of variability in a trait due to genes. Some traits are highly heritable (height) other less so (religion) Method: heritability assessed via family, twin study, monozygotic twin (identical, dizygotic twin (fraternal, adoptive studies. Genes make us more or less susceptible to environment influences. Account for individual differences in response to same environmental events. Genetic predisposition drives us to select particular environment. Mask the effects of nature: passive correlations: parents provide genotype and environment. Musically inclined parents often have children with more musical ability and enrolled their child in music lessons: evocative correlations: genetic traits elicit responses that reinforce that traits. A smiley outgoing child provokes friendly responses from strangers. Athletic child encourages to try out for a sport team: active correlations: child seeks out environments compatible with their genotype. Niche-picking: choosing environment that goes with their personality.
