Document Summary
Look at how environments differentially effect persons with different genotypes (ex. , reaction ranges) How genotypes are systematically related to different environmental conditions(ex. , gene- environments correlations) Investigates the in uence of heredity and environment on individual differences in human traits and development. Individuals genes may in uence environments to which they are exposed. As child ages, experiences extend beyond family. Some environments can mute or strengthen genetic traits. Biological parents, who are genetically related to child, provide rearing environment(big in infancy) Child"s/person"s characteristics elicit certain types of characteristics(lifespan) When children/people seek out environments they nd compatible and stimulating(increases with age) Childs own unique experiences, both within and outside of family, not shared by siblings. Development is the result of an ongoing, bidirectional interchange between heredity and environment. Each pair contains thousands of genes: one from father one from mother. Approximately 64 trillion different combinations per breeding people. Germinal period or period of the zygote.
