Which is incorrect in Mandelian characters ?

Options

A. `{:("Character","Dominant","Recessive"),("Pod colour","Green","Yellow"):}`
B. `{:("Character","Dominant","Recessive"),("seed shape","Round ","Wrinkled"):}`
C. `{:("Character","Dominant","Recessive"),("Flower position","Terminal","Axillary"):}`
D. `{:("Character","Dominant","Recessive"),("Shape of pod ","Full","Constricted"):}`

Answer

To determine which statement about Mendelian characters is incorrect, we will analyze the given options based on Mendel's experiments with pea plants. Here's a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding Mendelian Characters**: Mendelian characters refer to traits that follow the principles of inheritance established by Gregor Mendel through his experiments with pea plants. He identified dominant and recessive traits.

2. **Identifying the Traits**: Mendel studied seven pairs of contrasting traits in pea plants:
- Stem height: Dominant (Tall) and Recessive (Dwarf)
- Flower position: Dominant (Axial) and Recessive (Terminal)
- Pod color: Dominant (Green) and Recessive (Yellow)
- Pod shape: Dominant (Inflated) and Recessive (Constricted)
- Flower color: Dominant (Violet) and Recessive (White)
- Seed color: Dominant (Yellow) and Recessive (Green)
- Seed shape: Dominant (Round) and Recessive (Wrinkled)

3. **Evaluating the Options**: Now we will evaluate the options provided to identify the incorrect Mendelian character:
- **Option 1**: Pod color - Dominant (Green), Recessive (Yellow) - This is correct.
- **Option 2**: Seed shape - Dominant (Round), Recessive (Wrinkled) - This is correct.
- **Option 3**: Flower position - Dominant (Terminal), Recessive (Axial) - This is incorrect because the dominant trait is Axial, and the recessive trait is Terminal.
- **Option 4**: Pod shape - Dominant (Inflated), Recessive (Constricted) - This is correct.

4. **Conclusion**: The incorrect Mendelian character is from **Option 3**, where it states that the dominant flower position is Terminal. The correct dominant trait is Axial.

### Final Answer:
The incorrect Mendelian character is **Option 3: Flower position - Dominant (Terminal)**.
