Understanding the Relationship Between Heredity and Environment.
Explain the various ways heredity and environment may combine to influence complex traits.
Behavioural genetics is a field that examines the contributions of nature and nurture to complex traits. Researchers use kinship studies to compute heritability estimates, which show that genetic factors influence such traits as intelligence and personality. However, the accuracy and usefulness of heritability estimates have been challenged. According to the concepts of range of reaction and canalization, heredity influences children's responsiveness to varying environments. Genetic-environmental correlation and niche-picking describe how children's genes affect the environments to which they are exposed. Epigenesis reminds us that development is best understood as a series of complex exchanges between nature and nurture.
