Mendel failed to obtain the same results on

Options

A. Hawkweed
B. Lablab
C. Cucurbita pepo
D. Both (1)&(2)

Answer

To solve the question regarding which plants Mendel failed to obtain the same results in, we will analyze the plants mentioned and their modes of reproduction.

### Step-by-Step Solution:

1. **Understanding Mendel's Work**: Mendel is known as the father of genetics for his work on inheritance patterns in pea plants (Pisum sativum). He established the laws of heredity through his experiments on traits that were easily observable.

2. **Identifying the Plants**: The question mentions several plants, including Hawkweed and Lublub, and asks which ones Mendel could not obtain the same results in.

3. **Analyzing Hawkweed**:
- Hawkweed is known for a mode of reproduction called apomixis, which is a form of asexual reproduction.
- In apomixis, seeds are produced without fertilization, leading to offspring that are genetically identical to the parent.
- This means there is no genetic variation, which is essential for Mendel's experiments that relied on observing variations in traits.

4. **Analyzing Lublub**:
- Lublub also exhibits asexual reproduction, which similarly results in offspring that are clones of the parent plant.
- Like Hawkweed, this lack of genetic variation means Mendel's principles of heredity would not apply.

5. **Analyzing Cucurbita**:
- Cucurbita (commonly known as squash or pumpkin) is known for its sexual reproduction.
- This involves the fusion of gametes, leading to genetic variation, which is essential for Mendel's experiments.
- Therefore, Mendel would not have failed in this plant.

6. **Conclusion**:
- Since Mendel's experiments relied on sexual reproduction and genetic variation, he would have failed in Hawkweed and Lublub due to their asexual reproduction.
- The correct answer to the question is that Mendel failed to obtain the same results in Hawkweed and Lublub.

### Final Answer:
Mendel failed to obtain the same results in Hawkweed and Lublub (options 1 and 2).
