Assertion :- Mendel never supported blending inheritance.
Reason :- He found that the `F_(1)` always resembled either one of the parents.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are trur but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is Flase.
D. If both Assertion & Reason are false.

Answer

To solve the question regarding Mendel's stance on blending inheritance and the reasoning behind it, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understand the Assertion**: The assertion states that "Mendel never supported blending inheritance." This means that Mendel's experiments did not support the idea that offspring are a blend of parental traits.

2. **Understand the Reason**: The reason provided is that "he found that the F1 always resembled either one of the parents." This indicates that in Mendel's experiments, the first filial generation (F1) displayed traits that were distinctly from one parent or the other, rather than a mixture of both.

3. **Examine Mendel's Experiments**: Mendel conducted experiments using pea plants, focusing on traits such as flower color. For example, crossing a homozygous red flower (RR) with a homozygous white flower (rr) resulted in all F1 offspring being red (Rr), which supports the assertion.

4. **Contrast with Blending Inheritance**: Blending inheritance suggests that traits from both parents mix, leading to intermediate phenotypes (e.g., pink flowers from red and white parents). However, Mendel's findings showed that the F1 generation did not exhibit such blending; they resembled one parent (the red flower in this case).

5. **Conclude the Relationship**: Since Mendel's findings directly contradict the concept of blending inheritance, we can conclude that both the assertion and the reason are true. Moreover, the reason accurately explains why Mendel did not support blending inheritance.

6. **Select the Correct Option**: Based on our analysis, the correct option is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

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