To determine: The advantages of using Drosophila in the study of behavior genetics.
Introduction: The study of genetics and environmental influences on the behavior of an individual is called ‘behavioral genetics’. The genetics of human behavior can be studied through animal model systems. The animals are genetically similar to humans which are selected for developing an animal model for the particular disease.

Human Heredity: Principles and Issues (MindTap Course List)
- List some challenges associated with studying the genetics of behavior, and explain how linkage analysis, microarrays, and genome-wide association studies address some of those challengesarrow_forwardExplain why does only male mice used for testing behavioral studies, why not include the female mice and it is important to use both sex of mice for behavioral studies?arrow_forwardHow is the “NOR score” calculated for an animal? (i.e., monkey or rat)arrow_forward
- What are some ways to study mice? What happened when? For instance:arrow_forwardAnimal Models: The Search for Behavior Genes You are a researcher studying an autosomal dominant neurodegenerative disorder. You have cloned the gene underlying the disorder and have found that it encodes an enzyme that is overexpressed in the neurons of individuals who have the disorder. To better understand how this enzyme causes neurodegeneration in humans, you make a strain of transgenic Drosophila whose nerve cells overexpress the enzyme. a. How might you use these transgenic flies to try to gain insight into the disease or identify drugs that might be useful in the treatment of the disease? b. Can you think of any potential limitations of this approach?arrow_forwardDiscuss some methodological approaches that can be used to examine the influence of multiple genes on behavior. Please include peer reviewed references.arrow_forward
- In veterinary science What are 3 examples of mother nature's ID methods?arrow_forwardHow much of our behavior is determined by our genes versus the environment? Provide two examples of why or why not.What do you think are the pros and cons for an individual if they believe genes determine their behaviors? What are the pros and cons for individuals if they believe nature determines their behaviors? What do you think are the implications for society if we put a lot of weight on nature or nurture?arrow_forwardPeople with severe depression, mild depression, or no depression are included in GWAS research. Why not just look at those who have depression if the researchers are interested in genetic variations related with depression?arrow_forward
- Describe the methods used by behavior geneticists to study heredity’s influence on behaviorarrow_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_forwarddiscuss how computers are used in the selection and breeding of animals.arrow_forward
