Mendel was the first scientist to study the pattern of inheritance. He is known as the father of genetics and proposed the laws of inheritance. He selected pea plants (Pisum sativum) to carry out his study on the inheritance of characters from parents to offspring. Mendel carried the process of self-pollination followed by cross-pollination in his experiment.
Which of these is a dominant trait?

Options

A. tall
B. white
C. wrinkled
D. dwarf

Answer

To determine which of the traits mentioned is dominant, we can analyze the traits Mendel studied in his experiments with pea plants (Pisum sativum).

### Step-by-Step Solution:

1. **Understanding Mendel's Experiments**: Mendel conducted experiments on pea plants to study the inheritance of traits. He focused on several characteristics, including plant height, flower color, seed shape, and seed color.

**Hint**: Recall that Mendel's experiments involved observing how traits were passed from one generation to the next.

2. **Identifying the Traits**: The traits mentioned in the question are:
- Tall
- White
- Wrinkled
- Dwarf

**Hint**: Think about the characteristics Mendel identified as dominant and recessive.

3. **Dominant vs. Recessive Traits**: In Mendel's findings, he categorized traits into dominant and recessive. For example:
- **Height**: Tall (dominant) vs. Dwarf (recessive)
- **Flower Color**: Purple (dominant) vs. White (recessive)
- **Seed Shape**: Round (dominant) vs. Wrinkled (recessive)

**Hint**: Remember that dominant traits mask the expression of recessive traits in the phenotype.

4. **Analyzing the Given Traits**:
- **Tall** is a dominant trait over **Dwarf**.
- **White** is a recessive trait when compared to **Purple**.
- **Wrinkled** is a recessive trait when compared to **Round**.
- **Dwarf** is a recessive trait compared to **Tall**.

**Hint**: Look for traits that are known to be dominant in Mendel’s studies.

5. **Conclusion**: Among the traits listed (Tall, White, Wrinkled, Dwarf), the dominant trait is **Tall**.

**Final Answer**: The dominant trait is **Tall**.
