In one twin study investigating the genetics of addiction, 41% of monozygotic twins both exhibited substance dependence while 24% of dizygotic twins both exhibited substance dependence. Does this twin study suggest that there is or is not a genetic component to addiction? What evidence in model organisms supports a genetic component to addiction?

Why do you think it has been so difficult to identify genes underlying schizophrenia? 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.
What is Transcranial Magnetic Stimulation and how does it work? Imagine I predict that an area called the superior temporal gyrus in the right hemisphere is involved in face processing. How could I use TMS to help test my prediction? What does a heritability rate of 35% mean? How does the epigenome differ from the genome?
Does blood type determine your personality? In a study aimed at answering this question, a random sample of 100 adults was given a personality test, and a comparison was made between the scores on the introversion/extroversion scale and blood type (A, B, AB, О). (a) Is this an experiment, a retrospective observational study, or a prospective observational study? (b) Comment on the extent to which inferences can be drawn about a larger population and whether cause and effect can be established.
Monozygotic twins: Question 2 options: a) Share 50% of their genetic material and if one twin has schizophrenia the risk of the other having the illness if 40-50% b) Share 100% of their genetic material and if one twin has schizophrenia, the risk of the other having schizophrenia is 10-15% c) Share 100% of their genetic material and if one twin has schizophrenia, the risk of the other having schizophrenia is 40-50% d) Share 50% of their genetic material and if one twin has schizophrenia the risk of the other having the illness is 10-15%
In a study of schizophrenia (a mental disorder including disorganization of thought and withdrawal from reality), researchers looked at the prevalence of the disorder in the biological and adoptive parents of people who were adopted as children; they found the following results: Prevalence of schizophrenia Adoptees With schizophrenia Biological parents Adoptive parents 12 2 Without schizophrenia 6 4 [Source: S. S. Kety et al., 1978, in The Nature of Schizophrenia: New Approaches to Research and Treatment, L. C. Wynne, R. L. Cromwell, and S. Matthysse, Eds. New York: Wiley, 1978, pp. 25-37.] What can you conclude from these results concerning the role of genetics in schizophrenia? Explain your reasoning.
Researchers are starting to feel pretty confident that daily alcohol consumption is CAUSALLY linked with liver cancer. What do you think is the most important other Hill’s criterion that researchers would like to have that would make them feel even more strongly about causality in this relationship?
A researcher reads a news report about a high prevalence of diabetes among children residing in under resourced neighborhoods. The researcher wants to conduct a study to understand risk factors for diabetes in this population. They design a randomized controlled trial where children will be assigned to one group in which they are given 8 glasses of sugar sweetened beverages (SSB) per day (treatment group) and one group in which they are given 8 glasses of water per day (control group). The researcher goes to elementary schools in under resourced neighborhoods and approaches children as they are leaving the campus to tell they they have to participate in the study. The students are not told anything about the potential risks or benefits of study participation and are not compensated for being in the study. Drinking 8 glasses of water per day is known to be better for health compared to drinking 8 glasses of SSB per day. Because one treatment is already known to be more…
I'm having trouble finding the dependent and independent variables of this scenaro: Average IQ scores for young school children are known to be 100 (SD = 15). However, the literature indicates that children’s intelligence may be decreased if their mothers have German measles during pregnancy. Using hospital records, a researcher obtained a sample of n = 25 school children whose mothers all had German measles during their pregnancies. Do the data indicate that children born to mothers who had German measles during the pregnancy have significantly lower IQ scores than typical young school children?
Oxycontin is a drug used to treat pain, but it is well known for its addictiveness and danger. In a clinical trial, among randomly selected subjects treated with OxyContin, 52 developed nausea and 175 did not develop nausea. Among other randomly selected subjects given placebos, 5 developed nausea and 40 did not develop nausea. Use a 0.05 significance level to test the claim that the proportion of nausea is different for those on OxyContin than for those who are on placebo. Use the critical value method. Include a diagram of the distribution indicating important components of the question.
What is concordance? For a polygenic or multifactorial trait such as behavior, why are identical (monozygous) twins studied? What is the advantage of studying identical twins reared apart? What should be the concordance in identical twins raised apart if a trait is purely genetic with no environmental influence? What are some genetic conditions or chromosomal abnormalities that cause changes in behavior?For example, Huntington disease; Fragile X syndrome. What is schizophrenia and why is it considered multifactorial? What is autism? Major depression? Bipolar disorder? What is: the purpose of our immune system? Our first line of defense against infection? • What are some differences between our innate immune system, and our adaptive immune system? What is an antigen? An antibody? Which cells make antibodies? What is a memory B cell? How do vaccines work? Why must HLA be matched for a successful organ transplant? Why is it difficult to find a good match?
Larsen and Buss present four key research designs used in the behavioral genetic study of personality. Briefly review the key features of these designs and discuss the advantages and disadvantages of each design. Why would it be particularly powerful for a set of results (such as heritability and environmental estimates) to be documented using more than one design?
