1. If you were to compare the DNA of any two unrelated people, about what percent of their DNA would be identical? a. 25% b. 50% c. 99.9% d. 100% 2 Which of the following disorders occurs only when the gene involved is inherited from the mother and not the father? a. Prader-Willi syndrome b. Angelman syndrome c. Fragile X syndrome d. Down syndrome 3. Operant conditioning is especially likely to be involved in the development of: a. phobias b. excessive salivation c. habituation d. habits 4. Suppose that a human female is accidentally exposed to a poison at one of four different points in development. If the effect of the poison is that it interferes with meiosis, at which point in the lifespan would we expect it to have the most disruptive effect? a. in the prenatal period, since this is when ova are forming b. in the first year after birth, since this is when brain growth is most rapid c. during early adulthood, since this is when conception of a child is most likely to happen d. in older adulthood, since body cells are most vulnerable at the end of the lifespan 5. If different members of the family experience quite different environments, this would be reflected in: a. a larger shared environment b. a larger nonshared environment c. a harsher developmental niche d. a challenge for self-concept development 6. Which of the following is MOST likely to be experienced as a normative influence? a. retirement b. career change c. illness d. moving to a new community 7. Suppose that a disease is inherited. Your mother has the disease, your father does not, and you have a very minor case of the disease which lies somewhere in between your mother’s and father’s situation. In this case, we would know that the alleles that determine this trait: a. are recessive b. are dominant c. are codominant d. are heterozygous 8. Workers in Dr. Garcia’s lab first obtain tumor cells from patients with cancer. They then remove the DNA from the tumor cell nuclei and use enzymes to segment the DNA strands into sections. Finally, they insert the DNA sections in which they are interested into “host” bacteria cells, where the DNA can be reproduced for later use. Dr. Garcia’s lab is engaged in work involving: a. behavior genetics b. recombinant technology c. cryogenics d. autosomal transmission 9. Dr. Smith studies a group of 1,000 people who have schizophrenia and who also have identical twins. He finds that 47% of the identical twins also develop this disease. The type of statistical information Dr. Smith’s study reveals is called: a. concordance b. an H-E (Heredity-Environment) Index c. a genetic-based percentage d. analysis of variance 10. Patty doesn’t want to hang around with people from the other side of town because she says they are “weird.” Patty’s behavior best reflects the concept involved in: a. ethnocentrism b. self-efficacy c. normative age-graded influences d. normative history-graded influences
