In a study of schizophrenia (a mental disorder includingdisorganization of thought and withdrawal from reality), researcherslooked at the prevalence of the disorder in the biological and adoptiveparents of people who were adopted as children; they found thefollowing results:Prevalence of schizophreniaAdopteesWith schizophreniaBiological parents Adoptive parents122Without schizophrenia64[Source: S.

If a test were available that could tell you whether you were likely to develop a disorder such as schizophrenia later in life, would you take the test? Why or why not? Rachel asked to see a genetic counselor because she was concerned about developing schizophrenia. Her mother and maternal grandmother both had schizophrenia and were institutionalized for most of their adult lives. Rachels three maternal aunts are all in their 60s and have not shown any signs of this disease. Rachels father is alive and healthy, and his family history does not suggest any behavioral or genetic conditions. The genetic counselor discussed the multifactorial nature of schizophrenia and explained that many candidate genes have been identified that may be mutated in individuals with the condition. However, a genetic test is not available for presymptomatic testing. The counselor explained that based on Rachels family history and her relatedness to individuals who have schizophrenia, her risk of developing it is approximately 13%. If an altered gene is in the family and her mother carries the gene, Rachel has a 50% chance of inheriting it.
The biogenic amine hypothesis of schizophrenia suggests: Question 43 options: a) That changes in presynaptic neurotransmitter release, and postsynaptic receptor sensitivity, underlies the pathologic process in schizophrenia b) That a decrease in the amount of glutamate in the brain underlies the pathological process in schizophrenia c) That dysfunctional parenting in early childhood is an underlying pathological process towards the development of schizophrenia d) That highly expressed emotion, negative communication patterns, and emotionally involved families increase dopamine release, thereby causing schizophrenia

Concordance value with MZ twins is 46% and DZ twins is 14% for schizophrenia. What does this mean in terms of genetic and environmental components underlying schizophrenia?
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? a. The environment that a child grows up in causes schizophrenia b. Schizophrenia is an autosomal recessive disease c. An autosomal dominant allele…
