range of reaction
How have twin studies proven to be beneficial
researchers can determine the difference between environmental and genetic factors
Alcoholism is a type of
substance dependence
To be genetically predisposed to an illness means to be
susceptible to that illness
Who must understand comorbidity in children
teachers and parents
Why is it difficult for researchers to fully understand schizophrenia's genetic link
because no gene has been identified as responsible for the disorder and the role of the environment in this disease is not known
People are generally predisposed to
biological and behavioral issues
What term accurately describes Alzheimer's disease
complex disease
Researchers plan a study to find the proportion of identical twins that both suffer from depression. This is an example of the researchers determining the
concordance rate
A statistic for measuring how much a trait in one twin compares or contrasts with the same trait in the other twin is the
correlation coefficient
Hector's doctor says that her drug addiction can be treated but not cured. What model of addiction does he believe in
disease
Lonnie is addicted to alcohol. In order to treat him, his doctor has prescribed a drug that makes him very sick whenever he drinks alcohol. His doctor likely believes Lonnie fits what model of addiction
disease
The genetic perspective that investigates how similar genotypes can manifest into different phenotypes is known as what
epigenetics
When collecting samples to study the genetics of a complex disease, what factor would you not want to be equally represented in both the affected and unaffected groups
family history
In family studies, the proband refers to the
first person being studied
The biological building blocks of humans are known as
genes
What do twin studies generally reveal about the more complex human behaviors
genes and environment play a fairly equal role in influencing behavior
How do our genes affect our behavior
genes facilitate certain reactions to our environment

How are psychological disorders influenced by genetic factors
having a family history of psychopathologies puts a person in a higher risk category for developing a disorder than a person with no family history
The Minnesota Twin Study found that
identical twins raised apart are about as similar as those raised together
A geneticist is studying a genetic condition. They determine that the causative gene for this particular condition is located on human chromosome 2. What can be concluded about the condition
it is autosomal, because the condition is caused by a gene on one of the numbered chromosomes
If Brandon is genetically predisposed to diabetes, he
may get diabetes
What percentage of DNA do identical twins share
100% identical twins have the same DNA
How is psychopathology defined
A deviation from normal behavior or mental processes
Do genes or the environment influence traits
Genes AND the environment both influence traits
Why are twin studies useful in understanding human behavior
you can study subjects with the same genetics, but different environments
The genetic perspective that states our genes influence our environment, and our environment influences are genes is known as
the genetic environmental correlation
What is a primary condition in comorbidity
the principle cause of suffering and symptoms in a patient
What are multifactorial traits
they are usually determined by a combination of multiple genetic and non-genetic factors
Why are humans so unique in the animal kingdom
we take a very long time to develop
What question is important to ask in diagnosing comorbidity
what is the primary condition
What is comorbidity
when two or more conditions are simultaneously present in the same patient
