A: Geitonogamy helps in maintaining homozygosity and superiority of the race indefinitely
R: It is functionally ecologically and genetically cross pollination

Options

A. if both assetion A reason are ture and the reason is the correct explanation of the assertion then mark
B. if both assertion & reason are ture and the reason is not the correct explanation of the assertin then mark
C. if assertion is true statement but reason is false then mark
D. if both assertion and reason are flase statements then mark

Answer

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

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Geitonogamy helps in maintaining homozygosity and superiority of the race indefinitely."
- Geitonogamy is a type of pollination where pollen from one flower is transferred to another flower on the same plant.
- This process allows for self-fertilization, which promotes homozygosity (the condition of having identical alleles for a particular gene) because the genetic material comes from the same plant.

2. **Evaluating the Assertion**:
- Since geitonogamy involves pollen transfer within the same plant, it maintains genetic similarity and can lead to a stable and superior race over generations.
- Therefore, the assertion is **true**.

3. **Understanding the Reason (R)**:
- The reason states that "It is functionally ecologically and genetically cross-pollination."
- Cross-pollination typically refers to the transfer of pollen between different plants (xenogamy), which introduces genetic diversity.

4. **Evaluating the Reason**:
- Geitonogamy does not involve different plants; it involves different flowers of the same plant. Thus, it does not function as true cross-pollination because it does not introduce new genetic material from a different genetic source.
- Therefore, the reason is **false**.

5. **Conclusion**:
- Since the assertion is true and the reason is false, the correct answer is that the assertion is true while the reason is false.

### Final Answer:
- The correct answer is Option 3: Assertion is true, Reason is false.
