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 out (with respect to true breeding line)", we need to understand what a true breeding line is and how it functions in terms of inheritance. Here’s a step-by-step solution:

### Step 1: Define True Breeding Lines
True breeding lines are strains of organisms that, when self-pollinated, consistently produce offspring that exhibit the same traits as the parent. This means that the traits are stable and will not change over generations.

**Hint:** Remember that true breeding lines maintain consistent traits through generations.

### Step 2: Analyze the Options
We need to evaluate each option provided in the question to determine which one does not fit the definition of a true breeding line.

1. **Option 1:** This option likely describes a true breeding line that produces the same trait consistently.
2. **Option 2:** This option might suggest that the trait only expresses for a few generations, which contradicts the definition of true breeding.
3. **Option 3:** This option likely describes another true breeding line that produces the same trait consistently.
4. **Option 4:** This option may also describe a true breeding line.

**Hint:** Look for any option that suggests variability or inconsistency in trait expression.

### Step 3: Identify the Odd One Out
From the analysis, if option 2 states that it shows expression for only a few generations, it contradicts the definition of a true breeding line, which should show stable trait inheritance across all generations.

**Hint:** The odd one out will be the option that suggests limited expression or variability in traits.

### Step 4: Conclusion
Based on the analysis, option 2 is the odd one out as it does not align with the characteristics of true breeding lines.

**Final Answer:** Option 2 is the correct answer as it contradicts the definition of true breeding lines.
