70. Prior to the 1960’s, the environment (nurture) was thought to be the most important factor influencing mental health in humans. A key adoption study by Leonard Heston changed this view. Use Heston's data, shown below, to infer the relative importance of nature vs. nurture in the development of schizophrenia. Children given up by their birth mothers were adopted into households with normal (i.e., non-schizophrenic) parents so that all children were exposed to a similar environment while growing up. The incidence of schizophrenia in the adopted children is shown in the following table. Mental Health of Birth Mother Schizophrenic Mothers (n = 47) 5 adoptees developed schizophrenia 42 adoptees remained normal Normal Mothers (n = 47) O adoptees developed schizophrenia 47 adoptees remained normal What conclusion can you draw from this data?

The environment that a child grows up in causes schizophrenia b. Schizophrenia is an autosomal recessive disease c. An autosomal dominant allele causes schizophrenia d. Genes have some influence whether a person develops schizophrenia or not e. We cannot draw any conclusions about the role of the environment versus genes in causing schizophrenia 18
