Textbook Question
Chapter 19, Problem 19P
During a visit with your grandparents, they comment on how tall you are compared with them. You tell them that in your genetics class, you learned that height in humans has high heritability, although environmental factors also influence adult height. You correctly explain the meaning of heritability, and your grandfather asks, “How can height be highly heritable and still be influenced by the environment?” What explanation do you give your grandfather?

Like brown eyes, presence of dimples and cleft chin are dominant traits. Sarah has brown eyes and dimples, but no cleft chin. Her father has blue eyes but no dimples. She just married James who has blue eyes, dimples, and cleft chin. His mother has no cleft chin and his father has no dimples.
What is the genotype of Sarah?
What is the genotype of James?

Which of the following choices accurately describe what makes one person different from another with regard to traits (such as height) that have a very high heritability?
Choose all that apply
a) What makes us different is not that we have different genes, but that we have different alleles of many of those genes
b) What makes us different from each other is that we have different genes from each other
c) Random factors during development is the most significant causes of differences between people
d) Most of us have exactly the same genes and alleles, and it’s the environment we were raised in that makes us different
e) None of the other choices are accurate

- 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.arrow_forwardWe inherit many traits from our parents. Some physical traits we inherit are eye and hair color, height, skin color, and how big our ears are! We inherit other traits, traits we cannot see. These could include whether or not we are lactose intolerant or if we are prone to diabetes. Other traits we acquire or learn, like reading or how to use a computer.Question: Take a look at this family. Each parent has a different color hair, one blond and one brown. The two children also have blond or brown hair. How do we inherit hair color? Why do the children have the same hair color as their parents? Could these parents have two children with just brown hair? Explain.arrow_forwardWhich of the following statements about complex traits is/are TRUE? Twin studies help to tease apart the contribution of genetic and environmental factors to phenotypic variations. When describing quantitative traits, a high variance indicates that most individual values are not very close to the mean. Genetic factors determine Mendelian traits, while environmental factors determine complex traits. Both additive and dominant effect falls in the category of narrow sense heritability and can be directly passed on from parents to offspring.arrow_forward
- 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 religionarrow_forwardLarsen 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 questionarrow_forwardName: Human Phenotypes Simple dominance inheritance pattern: Q: How many phenotypes are evident in patterns of simple dominance? What are they? If a phenotype results from simple dominance, which two genotypes cannot be distinguished? Which phenotype is always representative of the genotype? Now determine your personal inheritance of the following traits. As you read through the following descriptions, you'll identify your trait, and determine your phenotype. Your trait will be one of the two Shape of the face. Most facial characteristics are affected by many different genes acting together (multiple factors or polygenic inheritance). For this trait we have simplified the nature of this trait by assuming it is the result of a single gene. Oval shape is dominant (needs only homozygous (both alleles are the same, either dominant or recessive) or heterozygous (one dominant allele and one recessive allele). Square shape is recessive (requires that both alleles are the recessive allele in…arrow_forward
- How does heritability differ between major trait categories such as morphology, life history, behavior, and physiology? Which trait types are generally most heritable and which are least heritable?arrow_forwardPerson A is color blind. This has developed The person Huntington's disease. mother of person A has normal vision and does not have Huntington's disease. B does not have Person Huntington's disease and has normal vision. The mother of Person B is normal for both traits, but the father is color blind and suffers from Huntington's disease. father of person A is not color The blind or has Huntington's disease. If persons A and B what and types proportions of children would be produced considering that the disease is lethal? marry,arrow_forwardClubfoot and spina bifida are traits best explained by the Threshold Model of complex traits. The Threshold Model explains the distribution of some complex traits. Only those individuals who have a genetic liability above a certain threshold are affected if exposed to certain environmental factors, such as continuous; maternal age continuous; maternal nutrition discontinuous; maternal nutrition discontinuous; maternal intelligence none of these are correctarrow_forward
- A genetics researcher determines that the broad-sense heritability of height among Southwestern University undergraduate students is 0.90. Which of the following conclusions would be reasonable? Explain your answer. a. Sally is a Southwestern University undergraduate student, so 10% of her height is determined by nongenetic factors. b. Ninety percent of variation in height among all undergraduate students in the United States is due to genetic differences. c. Ninety percent of the height of Southwestern University undergraduate students is determined by genes. d. Ten percent of the variation in height among Southwestern University undergraduate students is determined by variation in nongenetic factors. e. Because the heritability of height among Southwestern University students is so high, any change in the students’ environment will have minimal effect on their height.arrow_forwardWhat 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?arrow_forwardChoose a trait from the list above and describe if you are dominant or recessive for that trait. Do the same for your parents, alternatively, if you have children you can do this with your and your partner's traits and your child(ren), or you can choose a set of parents and children that you know as examples for this exercise. In your response be sure to list how both parents and their child(ren) are expressing the trait, what the potential GENOTYPES are for each individual. What are the possibilities for the parental pair based on their possible genotypes (hint: Punnet Square).arrow_forward
