Nearly 100 genes of this plant are similar to disease causing genes of humans

Options

A. Pisum sativum
B. Mirabilus jalapa
C. Antirrhinum majus
D. Arabidopsis thaliana

Answer

To solve the question, we need to identify which plant has nearly 100 genes that are similar to disease-causing genes in humans. Let's analyze the options provided step by step.

### Step 1: Analyze the first option - Pisum sativum
- **Pisum sativum**, commonly known as pea, is primarily a vegetable and is not known for having genes that are similar to disease-causing genes in humans.
- **Conclusion**: This option is incorrect.

### Step 2: Analyze the second option - Mirabilis jalapa
- **Mirabilis jalapa**, also known as the four o'clock plant, is an ornamental plant. It does not have a significant association with disease-causing genes in humans.
- **Conclusion**: This option is also incorrect.

### Step 3: Analyze the third option - Antirrhinum majus
- **Antirrhinum majus**, commonly known as snapdragon, is a flowering plant. Similar to the previous options, it does not have a known connection to disease-causing genes in humans.
- **Conclusion**: This option is incorrect as well.

### Step 4: Analyze the fourth option - Arabidopsis thaliana
- **Arabidopsis thaliana** is a small flowering plant that is widely used as a model organism in plant biology and genetics. It has been found to have many genes that are similar to those associated with diseases in humans, particularly in the context of studying plant-pathogen interactions and defense mechanisms.
- **Conclusion**: This option is correct.

### Final Answer
The correct answer is **Arabidopsis thaliana**.
