1. 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.

2. What is the result when a single zygote separates into two parts, each developing into a separate individual?

• A. Dizygotic twin
• B. Monozygotic twin
• C. Fraternal twin
• D. Nonidentical twin

Correct answer: B

Rationale: The correct answer is B, Monozygotic twin. A monozygotic twin, also known as an identical twin, is the result when a single zygote splits into two parts, leading to the development of two genetically identical individuals. Choices A, C, and D are incorrect because they do not accurately describe the scenario where a single zygote splits into two parts to form identical twins. Dizygotic twin (Choice A) refers to fraternal twins, which result from two separate eggs fertilized by two different sperm cells. Fraternal twin (Choice C) is another term for dizygotic twins, arising from two separate zygotes. Nonidentical twin (Choice D) is a synonymous term for dizygotic or fraternal twins, indicating that they are not genetically identical.

3. Which of the following psychologists would be most likely to stress that each person has a drive to grow and fulfill his or her potential?

• A. Sigmund Freud
• B. F. Skinner
• C. G. Stanley Hall
• D. Abraham Maslow

Correct answer: D

Rationale: The correct answer is D, Abraham Maslow. He was a leading humanist psychologist who introduced the concept of the hierarchy of needs. Maslow emphasized the human drive for self-actualization, which involves fulfilling one's potential and striving for personal growth. Sigmund Freud (choice A) focused on psychoanalysis and the unconscious mind. B.F. Skinner (choice B) was a behaviorist who studied operant conditioning. G. Stanley Hall (choice C) was a pioneering psychologist in the field of child development.

4. Albert has brown eyes, even though one of his biological parents has blue eyes. Genes for blue eyes are part of Albert's ___.

• A. Phenotype
• B. Zygote
• C. Genotype
• D. Environment

Correct answer: C

Rationale: Albert's genotype refers to the genetic makeup inherited from his parents, which includes the genes for blue eyes. The phenotype, on the other hand, is the observable trait, in this case, brown eyes. Therefore, the correct answer is C. Choice A (Phenotype) is incorrect as it refers to the observable characteristics, not the genetic information. Choice B (Zygote) is incorrect as it refers to the initial stage of a developing organism. Choice D (Environment) is incorrect as it does not directly determine eye color.

5. Which of the following is an appropriate description of a child with conduct disorder?

• A. They may argue repeatedly with adults, ignore adult rules and requests, deliberately annoy other people, and feel much anger and resentment
• B. They have great difficulty attending to tasks, or behave overactively and impulsively, or both
• C. Marked by extreme unresponsiveness to other people, severe communication deficits, and highly rigid and repetitive behaviors, interests, and activities
• D. They are often aggressive, deliberately destroy other people's property, steal or lie, skip school, or run away from home

Correct answer: A

Rationale: The correct answer is A. Children with conduct disorder often exhibit behaviors such as arguing with adults, ignoring rules, deliberately annoying others, and displaying anger and resentment. Choice B describes symptoms more characteristic of ADHD (Attention-Deficit/Hyperactivity Disorder). Choice C describes symptoms commonly seen in individuals with autism spectrum disorders. Choice D outlines behaviors associated with oppositional defiant disorder rather than conduct disorder.
