Q1. What is the term used by Dawkins to describe the effect of genes on the environment beyond the organism itself?
- A. Gene Expression
- B. Extended Phenotype ✓
- C. Morphological Trait
- D. Genetic Code
Why: Dawkins introduces the concept of the extended phenotype to describe how genes influence the environment through the organism's behavior and other effects.
Q2. According to Dawkins, which of the following is NOT a characteristic of the extended phenotype?
- A. It can be behavioral
- B. It is always visible ✓
- C. It can affect other organisms
- D. It can be non-physical
Why: The extended phenotype does not have to be visible, as it includes non-physical effects such as behaviors that influence the environment.
Q3. In the context of the extended phenotype, what role does the environment play?
- A. It is the sole determinant of genetic expression
- B. It is shaped by the organism's genes ✓
- C. It has no influence on the phenotype
- D. It is independent of genetic factors
Why: The extended phenotype concept suggests that genes can shape the environment, which in turn affects the organism and other organisms.

- A. Genes are solely responsible for physical traits
- B. Genes influence the environment through the organism ✓
- C. Genes are unaffected by the environment
- D. Genes only affect the organism's internal structure
Why: Dawkins argues that genes influence the environment through the organism's actions, which is a central idea of the extended phenotype.

- A. The physical structure of organisms
- B. The influence of genes on the environment ✓
- C. The genetic makeup of individuals
- D. The role of natural selection in evolution

Q1. What is the term used by Dawkins to describe the effect of genes on the environment beyond the organism's body?
- A. Genotype
- B. Extended Phenotype ✓
- C. Phenotype
- D. Epigenotype
Why: Dawkins introduces the concept of the extended phenotype to explain how genes influence the environment in ways that go beyond the physical traits of the organism.

- A. A bird's beak shape
- B. A beaver's dam ✓
- C. A human's eye color
- D. A plant's leaf size
Why: A beaver's dam is considered an extended phenotype because it is a product of the beaver's genes and influences the environment in which the beaver lives.
Q3. What is the main purpose of the extended phenotype concept according to Dawkins?
- A. To explain genetic inheritance
- B. To show how genes can influence the environment ✓
- C. To classify different species
- D. To study human behavior
Why: The extended phenotype concept is used to illustrate how genes can affect the environment in ways that go beyond the organism's body, influencing other organisms and the physical environment.
Q4. Which of the following is NOT considered an extended phenotype?
- A. A spider's web
- B. A termite mound
- C. A human's brain ✓
- D. A bird's nest
Why: A human's brain is not considered an extended phenotype because it is part of the organism itself, not an external modification of the environment.
Q5. What does Dawkins argue about the extended phenotype in relation to natural selection?
- A. It is irrelevant to natural selection
- B. It is a direct result of natural selection ✓
- C. It weakens the concept of natural selection
- D. It complicates the concept of natural selection
Why: Dawkins argues that the extended phenotype is a direct result of natural selection, as genes that influence the environment in beneficial ways are selected for over time.

Q1. What is the extended phenotype according to Dawkins?
- A. The physical traits of an organism
- B. The effects of genes on the environment beyond the body of the organism ✓
- C. The genetic makeup of an organism
- D. The behavior of an organism
Why: The extended phenotype refers to the effects of genes on the environment outside the organism's body, such as nest building by birds or the formation of termite mounds.
Q2. Which of the following best describes the role of genes in the extended phenotype?
- A. They only influence traits inside the organism
- B. They influence traits both inside and outside the organism ✓
- C. They have no influence on the environment
- D. They only influence the behavior of other organisms
Why: Genes influence traits both within the organism and outside, such as the construction of structures by organisms.
Q3. What is an example of an extended phenotype?
- A. A human's eye color
- B. A beaver's dam ✓
- C. A plant's root system
- D. A bird's feathers
Why: A beaver's dam is an example of an extended phenotype, as it is a product of the beaver's genes influencing the environment beyond its own body.
Q4. According to Dawkins, what is the primary unit of selection in evolution?
- A. The organism
- B. The gene ✓
- C. The species
- D. The environment
Why: Dawkins argues that the gene is the primary unit of selection in evolution, as it is the gene that is passed on and subject to natural selection.
Q5. Which of the following is NOT considered part of the extended phenotype?
- A. A bird's nest
- B. A spider's web
- C. A human's brain ✓
- D. A coral reef
Why: The human brain is part of the organism itself and is not considered part of the extended phenotype, which refers to effects outside the organism's body.
