Mark th odd one (w.r.t true breeding line)

Options

A. Shows the stable trait inheritance
B. Shows expression for few generations only
C. Undergone continous self-pollination
D. Both (1) & (3)

Answer

To solve the question, "Mark the odd one (w.r.t true breeding line)," we will analyze each option provided in relation to true breeding lines.

### Step-by-Step Solution:

1. **Understand True Breeding Lines**:
- True breeding lines, also known as pure lines, are organisms that consistently pass down specific traits to their offspring over many generations. This means that if you breed two true breeding individuals, their offspring will exhibit the same traits as their parents.

**Hint**: Remember that true breeding lines maintain stable traits over generations.

2. **Evaluate the First Option**:
- The first option states that true breeding lines show stable trait inheritance. This is a true statement because true breeding lines are characterized by their ability to consistently express specific traits.

**Hint**: Look for statements that align with the definition of true breeding.

3. **Evaluate the Second Option**:
- The second option claims that true breeding lines show expression for few generations only. This is false because true breeding lines exhibit stable inheritance over several generations, not just a few.

**Hint**: Identify statements that contradict the definition of true breeding.

4. **Evaluate the Third Option**:
- The third option states that true breeding lines undergo continuous self-pollination. This is true because true breeding lines are often maintained through self-pollination, which helps preserve the genetic traits.

**Hint**: Consider how true breeding lines are propagated.

5. **Evaluate the Fourth Option**:
- The fourth option mentions both 1 and 3. Since both statements are true, this option cannot be the odd one out.

**Hint**: Check if the option combines true statements.

6. **Identify the Odd One Out**:
- Based on the evaluations, the second option is the odd one out because it incorrectly states that true breeding lines show expression for few generations only, which contradicts the definition of true breeding lines.

**Final Answer**: The odd one out is the second option.

### Summary of the Solution:
- The odd one with respect to true breeding lines is the statement that they show expression for few generations only. True breeding lines exhibit stable inheritance over many generations.
