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?

Select one: O a. Both alleles are expressed only when they are homozygous O b. Each allele is both dominant and recessive O c. The alleles are neither dominant nor recessive O d.

Thus the norm of reactionas a whole—rather than any one phenotype—determines ifselection is positive or negative.”arrow_forward
- A geneticist is studying memory recall and is trying to locate specific genes that have varying effects on a given phenotype (physical trait) in the study subjects. These locations of these genes are referred to as: Group of answer choices Genomic spatial identifications Epigenetic regulators Evocative response indicators Quantitative trait lociarrow_forwardOne of the models for behavioral traits in humans involves a form of gene interaction known as epistasis. What is epistasis?arrow_forwardTwin 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_forward
