1. In order for one to have a recessive trait (e.g., having red hair), the person must receive?

• A. At least one copy of a recessive gene from a parent
• B. Two copies of a recessive gene, one from each parent
• C. At least one copy of a recessive gene and at least one copy of a dominant gene
• D. At least two copies of a recessive gene from one parent

Correct answer: B

Rationale: Recessive traits are expressed when an individual inherits two copies of the recessive gene, one from each parent. Therefore, the correct answer is B. Choice A is incorrect as one copy of a recessive gene is not sufficient to display a recessive trait. Choice C is incorrect because having at least one copy of a dominant gene is unrelated to expressing a recessive trait. Choice D is incorrect because two copies of a recessive gene must come from both parents, not just one.

2. Down syndrome is caused by ________

• A. a chemical imbalance.
• B. a gene on the X chromosome.
• C. possessing an extra X chromosome.
• D. possessing an extra chromosome in chromosome 21.

Correct answer: D

Rationale: Down syndrome is caused by possessing an extra chromosome in chromosome 21, not a chemical imbalance (choice A), a gene on the X chromosome (choice B), or possessing an extra X chromosome (choice C). The presence of an extra copy of chromosome 21, also known as trisomy 21, leads to the characteristic features and health problems associated with Down syndrome.

3. What research method involves researchers using interviews and/or questionnaires to collect data about attitudes, interests, values, and various kinds of behaviors?

• A. Case study
• B. Survey
• C. Naturalistic observation
• D. Correlational study

Correct answer: B

Rationale: The correct answer is B: Survey. A survey is a research method where data is collected through interviews or questionnaires about various behaviors and attitudes. In a case study (choice A), researchers closely examine a particular individual or group. Naturalistic observation (choice C) involves observing subjects in their natural environment. Correlational study (choice D) examines the relationship between two variables but does not involve collecting data through interviews or questionnaires.

4. When the parent returned in the strange situation experiment, babies with ____ attachment tend to remain upset for long periods of time, kicking, screaming, refusing to be distracted with toys, and sometimes arching back and away from contact?

• A. Secure
• B. Avoidant
• C. Ambivalent
• D. Disorganized

Correct answer: C

Rationale: In the strange situation experiment, babies with ambivalent attachment display distress and have difficulty calming down when a parent returns. They may kick, scream, refuse toys, and show signs of physical discomfort or resistance. This behavior is characteristic of ambivalent attachment, where the infant shows mixed emotions and finds it hard to be soothed by the returning parent. Secure attachment (Choice A) refers to babies who seek comfort from the parent but can be soothed upon return. Avoidant attachment (Choice B) involves babies showing little emotion upon reunion with the parent. Disorganized attachment (Choice D) displays inconsistent or confused behaviors in the strange situation experiment.

5. An inborn trait that is relatively permanent and differentiates one person from another is known as ________.

• A. genotype
• B. phenotype
• C. temperament
• D. characteristic

Correct answer: C

Rationale: Temperament is the correct answer because it refers to an individual's inborn, relatively permanent trait that distinguishes one person from another. Genotype (choice A) refers to the genetic makeup of an organism, not necessarily a behavioral trait. Phenotype (choice B) is the observable characteristics of an organism resulting from the interaction between its genotype and the environment. Characteristic (choice D) is a broad term that can encompass various traits and features, but it does not specifically denote an inborn and relatively permanent trait that sets individuals apart.
