1. What is a person's total genetic endowment?

• A. Phenotype
• B. Genotype
• C. Chromosomes
• D. DNA

Correct answer: B

Rationale: The correct answer is B: Genotype. A genotype refers to a person's total genetic endowment, representing the specific genetic makeup inherited from their parents. This includes all the genes and genetic information contained in an individual's DNA. Choices A, C, and D are incorrect because: A) Phenotype refers to the observable characteristics resulting from the interaction of genetics and the environment; C) Chromosomes are physical structures that contain genes, not the total genetic endowment itself; D) DNA carries genetic information but is just one component of an individual's total genetic endowment.

2. Dr. Fox studies the causes of depression. In other words, she looks at factors that play a role in the ________ of depression.

• A. etiology
• B. epidemiology
• C. prevalence
• D. resiliency

Correct answer: A

Rationale: The correct answer is A, 'etiology.' Etiology specifically deals with the causes or origins of diseases like depression. Choice B, 'epidemiology,' focuses on the patterns, causes, and effects of health and disease conditions in defined populations. Choice C, 'prevalence,' refers to the proportion of a population found to have a condition. Choice D, 'resiliency,' relates to the ability to recover from or adjust to challenges.

3. Which of the following is not a common method for studying genetic influences?

• A. The study of specific gene defects
• B. Twin studies
• C. Adoption studies
• D. Family history (pedigree) studies

Correct answer: A

Rationale: The correct answer is A. Studying specific gene defects is not a common method for investigating genetic influences. Choices B, C, and D are common methods used in genetic research. Twin studies help determine the heritability of traits, adoption studies compare similarities between adopted individuals and their adoptive families versus biological families, and family history studies track the inheritance patterns of traits within families.

4. Which of the following is a common effect of persistent discrimination?

• A. Increased happiness
• B. Greater intelligence and wisdom
• C. Cardiovascular reactivity
• D. Increased consciousness

Correct answer: C

Rationale: The correct answer is C: Cardiovascular reactivity. Persistent discrimination can have negative impacts on an individual's physical health, leading to increased cardiovascular reactivity. This can manifest as higher blood pressure, heart rate, and overall stress on the cardiovascular system. Choices A, B, and D are incorrect because persistent discrimination typically does not result in increased happiness, greater intelligence and wisdom, or increased consciousness. Instead, it often leads to detrimental effects on mental and physical health.

5. What is the term for a fluid-filled sac in which the baby floats until just before it is born?

• A. Amnion
• B. Placenta
• C. Umbilical cord
• D. Embryo

Correct answer: A

Rationale: The correct answer is A: Amnion. The amnion is a fluid-filled sac that surrounds and protects the developing fetus in the womb. It acts as a cushion, maintaining a stable temperature and protecting the fetus from external pressure. Choices B, C, and D are incorrect because the placenta is an organ that provides nutrients and oxygen to the fetus and removes waste products, the umbilical cord connects the fetus to the placenta to facilitate nutrient exchange, and an embryo is an early stage of development before it becomes a fetus.
