- The relationships between the big five traits and health are complicated. In lecture we learned that negative emotionalityand extroversion are related to health, but what has some of the strongest direct relationships.The effects of poverty, stress, racism, or socioeconomic status have not been conflated with the effects of genetics or ancestry. True FalseIf a dominant disorder is described as being 80% penetrant, what would this mean? The amount of expression within individuals varies O The disorder is present in 20% of the individuals that have the dominant allele 20% of the individuals who have the dominant allele may have genes that mitigate (prevent) the disorder and therefore do not display symptoms O The trait is present in 80% of the total population.
- What extent do genes predispose our individual personality differences?Twin studies are often used in the research of human behavioral traits. Although helpful, there are limitations to these studies. All of the following are limitations to twin studies EXCEPT: Traits are assumed to be simple Mendelian inheritance, discounting additive alleles and epistasis Dizygotic twins will often share more than 50% of their genes Monozygotic twins are often treated more similarity than dizygotic twins O Twins studies are a mechanism to understand the genetic and environmental components of a trait Twins reared apart are often adopted out to families of similar income, ethnicity, and religionWhat is the positive ways that inherited factors are indispensable in determining the appearance of an individual
- If the frequency of the aa genotype is 11%, what is the frequency of the AA genotype? Assume that there are only two alleles (i.e. a and A).Briefly describe common misunderstandings or misapplications of the concept of heritabilitySelect all the characteristics that make sickle-cell disease a good candidate to study genetic diseases. (Check all that apply.) Check All That Apply It is easily identifiable by a physical characteristic.It is easily identifiable by a physical characteristic. It results from a single change in a single gene.It results from a single change in a single gene. It can be influenced by the environment.It can be influenced by the environment. The sickle-cell inheritance pattern is not influenced by other genes.The sickle-cell inheritance pattern is not influenced by other genes.
- 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? Refer to a specific personality trait in formulating your answer to this questionCystic fibrosis is a homozygous recessive condition that affects 1 in 10,000 of the Hispanic populationin the United States. Calculate the frequency of the dominant allele, the frequency of the recessiveallele, and the percentage of heterozygous individuals (carriers) in the Hispanic population.Frequency of thedominant alleleFrequency of therecessive allele% homozygous dominant% homozygous recessive% heterozygousCharacteristics can be impacted by both genetic and environmental factors. What is one piece of evidence that can be used to show this?
