Which of the statement is not true for Genetic Drift

Options

A. It is non-directional force
B. It causes sudden fluctuations in a small group of population
C. The allelic combination of founders may be enhanced in a new pollution
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Genetic Drift**:
- Genetic drift refers to the random changes in allele frequencies within a population, particularly in small populations. It can lead to significant changes over time due to chance events.

2. **Identifying the Characteristics of Genetic Drift**:
- Genetic drift is non-directional, meaning it does not favor any particular allele or trait.
- It often results in sudden fluctuations in allele frequencies, especially in small populations.
- The founder effect is a specific type of genetic drift that occurs when a small group from a larger population establishes a new population, potentially leading to different allele frequencies.

3. **Evaluating the Statements**:
- The question asks which statement is NOT true regarding genetic drift.
- We need to analyze each option provided in the question to determine its validity.

4. **Analyzing Each Option**:
- **Option 1**: Genetic drift is non-directional. (True)
- **Option 2**: It causes sudden fluctuations in small groups. (True)
- **Option 3**: The allelic combination of the founder may be enhanced in a new population. (True)
- **Option 4**: None of these statements are false. (True)

5. **Conclusion**:
- Since all the statements provided are true regarding genetic drift, the correct answer to the question "Which of the statements is not true for Genetic Drift?" is **Option 4: None of these**.
