• 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. Dr. Haldol has several patients with schizophrenia who appear to exhibit excessive or distorted characteristics in relation to what one might consider normal functioning. Specific symptoms include varied hallucinations and multiple delusions. According to the DSM-5, these are referred to as?

• D. Theoretical perspectives are only relevant for academic research, not for clinical practice.

Correct answer: A

Rationale: The selection of a theoretical perspective matters because it determines how data is interpreted and influences the treatment approaches that are considered appropriate. Choice B is incorrect because different perspectives may lead to different interpretations and treatment strategies. Choice C is incorrect because different theoretical perspectives can result in varied treatment outcomes. Choice D is incorrect because theoretical perspectives play a crucial role in both academic research and clinical practice.

Gestational age is calculated from the first day of the expectant mother's last menstrual cycle, providing an estimate of how far along the pregnancy is. Mental age (choice A), refers to an individual's level of cognitive functioning in relation to others of the same age group. Chronological age (choice B) is a person's actual age in years. Functional age (choice C) refers to how well a person is able to perform various activities compared to their chronological age.

5. Normal human cells have ________

• A. twenty-two chromosome pairs and one pair of sex chromosomes.
• B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
• C. twenty-one chromosome pairs and two trisomy chromosome pairs.
• D. twenty-three chromosome pairs.

Correct answer: A

Rationale: Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This is the correct answer as it accurately describes the typical chromosome count in human cells. Choice B is incorrect because it mentions 'twenty-one trisomy chromosome pairs,' which is not characteristic of normal cells. Choice C is incorrect as it suggests having 'two trisomy chromosome pairs,' which is abnormal. Choice D is incorrect as it states 'twenty-three chromosome pairs,' which is not the standard count in normal human cells.
