Document Summary
Jan 21 lecture 3 biology, behaviour and development. Nature and nurture (posting questions about the cause- we are predisposed to ask these questions and expect a simple answer) Both heredity and environment influence individuals" characteristics. When scientists first began to investigate the contribution of heredity and environment, they generally emphasized one factor or the other as the prime influence. Recent efforts to map the human genome established that individuals differ from one another by only about 1-1. 5% of their genes. The science concerned with how variation in behaviour and development results from the combination of genetic and environmental factors. Answer: behavioural traits are heritable influenced by hereditary factors. Genetic and environmental forces (interplay between gens and experience is very complex) Genetics and environmental influence: parents" genetic contribution to the child"s genotype, contributions of the child"s genotype to his or her own phenotype, contribution of the child"s environment to his or her own phenotype.
