BEHAVIORAL GENETICS As you know, we investigated the nature side of the nature-nurture issue by studying the genetic contribution to behavior. We looked at the "Behavioral Genetics" sub-field of modern psychology. You should be able to describe this field of study and what researchers are looking for - i.e., possible links between genetic endowment and behavior/personality. 23 pairs (46 total) of chromosomes that contain the secret codes that determine many aspects of us, both physically and psychologically. The code in the genes on the chromosomes and the code is made up of DNA molecules. DNA molecules are made up of what four chemical bases? – guanine/cytosine, thymine/adenine Know the helix shape. Know how DNA replicates (i.e., by unzipping. .. I discussed it in class) What is the Human Genome Project? What was its goal? - Gene/chromosome studies- specific genes, bad sections of dna, missing chromosomes,  extra chromosome<(down syndrome) You should know the basic research techniques used by behavioral geneticists - Family incidence – compare the incidence of relatives  having a characteristic to the  incidence in the general population . . genetics/env. - Adoption – compare characteristics of offspring when char. of biological and adoptive  parents - Twin studies – compare incidence of char. in twins.   Monozygotic – single egg – identical Dyzygotic – two eggs - fraternal You should really understand and be able to explain why studying identical twins reared apart is the most important and valuable technique for teasing apart the biological from the learning contributions to us and our behavior. Is there genetic evidence that intelligence has a genetic link? personality?
