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?
