Chapter 18, Problem 2QP
Summary Introduction
To determine: The statement that accuracy is an important factor to define a trait in human behavior genetics.
Introduction: The study of genetics and environmental influences on the behavior of an individual is called ‘behavioral genetics’. Interactions among environmental stimuli, genes, and nervous system result in human behavior.

In behavioral genetics research, a gene already known to be related to some behavior is referred to as a(n):
Group of answer choices
Candidate gene
Polygenic gene
Warrior gene
Evocative gene
What 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?
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 religion
