Question 1

Why is cyclic AMP considered important in behavioral studies?

Accepted Answer

Cyclic AMP affects short-term

Question 2

One of the oldest recorded behavior mutants is the waltzer mutation in the mouse.Mutant mice can be observed "dancing" and "head shaking"; some are also deaf.Mice must be homozygous for a mutation to express the trait.Based on this information,the genetic cause of this trait is most likely a(n)________.

Accepted Answer

A)  simple recessive pattern of inheritance 
B)  multifactor, polygenic pattern of inheritance 
C)  dominant/recessive pattern typical of other behavioral traits 
D)  epistatic pattern with incomplete dominance 
E)  variable gene activity pattern with overdominance causing deafness

Question 3

Huntington disease (HD)is a well-studied,autosomal dominant disorder that affects the nervous system.Symptoms usually appear after age 40,and victims usually die within 10 to 15 years after onset of the disease.It appears that at least in some cases of HD,"stutter" mutations occur.Such mutations are characterized by ________.

Accepted Answer

A)  uncontrolled verbal capacity of patients 
B)  extra trinucleotide repeats within the HD gene 
C)  RNA polymerase imperfections leading to altered DNAs 
D)  repeated DNA polymerases generating too many coding symbols 
E)  links between monoamine oxidase A (MAO
A)  and hexokinase

Question 4

Research on alcoholism indicates that at least in mouse and animal models,a single dominant gene is responsible.

Accepted Answer

A) True 
 B)False

Question 5

Determining the genetic influence on two fairly common human behavioral disorders has eluded researchers for many years.One involves passive deficits in thinking,language,feelings,and social skills; the other includes a variety of psychotic symptoms,perceptual disorders (hearing voices),and withdrawal from reality.Evidence from pedigrees and twins indicates that these two behaviors have a genetic component.Which behaviors are being described here?

Accepted Answer

autism and

The availability of a large series of monozygotic and dizygotic twins often enhances studies on the genetic basis of human behavior.

Accepted Answer

A) True 
 B)False

Question 8

What is a major problem that arises in the study of the genetic basis of human behavior?

A)  Memories of individuals are unreliable. 
B)  People are too short lived. 
C)  Behaviors are difficult to define objectively. 
D)  The environment plays no role in behavioral expression. 
E)  The environment is the only factor that determines human behavior.

B)  No single gene or allele makes a significant contribution. 
C)  A single recessive gene is involved. 
D)  Several dominant genes located on the X chromosome cause this disease. 
E)  No more than three loci are involved in the expression of schizophrenia.
