Assertion : Cross pollination in true genetic sense within species is called xenogamy .
Reason : When there is cross pollination , resultant hybrids is a combination of characters of two plants.

Options

A. If both Assertion and Reason are the true and Reason is correct explanation of Assertion .
B. If both Assertion and Reason ar ture but Reason is not correct explanation of Assertion .
C. If Assertion is true but Reason is false .
D. If both Assertion and Reason are false .

Answer

To analyze the given statements, we will break down the assertion and the reason step by step.

### Step 1: Understanding the Assertion
- The assertion states that "Cross pollination in true genetic sense within species is called xenogamy."
- Cross pollination refers to the transfer of pollen grains from the anther of one flower to the stigma of another flower, which can occur between different plants of the same species or different species.
- Xenogamy specifically refers to cross pollination that occurs between different individuals of the same species, ensuring genetic diversity.

**Hint for Step 1:** Look up definitions of cross pollination and xenogamy to understand their meanings clearly.

### Step 2: Understanding the Reason
- The reason states that "When there is cross pollination, the resultant hybrid is a combination of characters of two plants."
- This means that when two different plants undergo cross pollination, they produce offspring (hybrids) that exhibit traits from both parent plants.
- This is a fundamental principle of genetics where traits from both parents combine to form a new genetic makeup in the offspring.

**Hint for Step 2:** Consider how traits are inherited from parents to offspring in plants and the concept of hybridization.

### Step 3: Evaluating the Relationship Between Assertion and Reason
- Both the assertion and the reason are true statements.
- The reason correctly explains the assertion because the process of xenogamy (cross pollination) indeed results in hybrids that carry genetic information from both parent plants.

**Hint for Step 3:** Think about how the process of hybridization contributes to genetic variation and the significance of cross pollination in plant reproduction.

### Step 4: Conclusion
- Based on the evaluation, the correct conclusion is that both the assertion and the reason are true, and the reason is the correct explanation of the assertion.

**Final Answer:** Both assertion and reason are true, and the reason is the correct explanation of the assertion.
