A: Endogamy is common is majority of animals
R: Fusing gametes are quite different and develop from the different individuals

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1)
B. If both Assertion & Reason are true and the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statements but Reason is false then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To solve the assertion and reason question, we will analyze both statements step by step.

### Step 1: Understand the Assertion
The assertion states: "Endogamy is common in the majority of animals."
- **Definition of Endogamy**: Endogamy refers to the fusion of gametes from the same individual or closely related individuals. In animals, this would mean that mating occurs within a specific group or population, leading to inbreeding.

### Step 2: Evaluate the Truth of the Assertion
- In reality, endogamy is not common in the majority of animals. Most animal species tend to practice exogamy, which involves mating with unrelated individuals to promote genetic diversity. Therefore, the assertion is **false**.

### Step 3: Understand the Reason
The reason states: "Fusing gametes are quite different and develop from different individuals."
- This statement describes the process of exogamy, where gametes from different individuals fuse together, leading to greater genetic variation.

### Step 4: Evaluate the Truth of the Reason
- Since the reason describes exogamy rather than endogamy, it does not correctly explain the assertion. Additionally, it is also **false** in the context of endogamy because, in endogamy, the gametes come from the same individual.

### Step 5: Conclusion
Both the assertion and the reason are false. Therefore, the correct answer is that both the assertion and reason are false statements.

### Final Answer
Both assertion and reason are false.
