Genetic drift / Sewell Wright effect is a_______process.

Options

A. random
B. directed
C. revolutionary
D. uniformitarian

Answer

**Step-by-Step Solution:**

1. **Understanding Genetic Drift**: Genetic drift refers to the changes in allele frequencies within a population due to random sampling of organisms. It is a mechanism of evolution that can lead to significant changes in small populations.

2. **Identifying the Nature of Genetic Drift**: The question asks about the nature of genetic drift, specifically if it is random, directed, or evolutionary.

3. **Analyzing the Options**: The options given are:
- Random
- Directed
- Re-evolutionary
- Uniform
- Mature
- Re-Un

4. **Determining the Correct Option**: Genetic drift is characterized by random changes in allele frequencies. This randomness means that the changes are not influenced by the fitness of the alleles, but rather occur by chance events.

5. **Conclusion**: Based on the understanding of genetic drift, the correct answer is that genetic drift (or the Sewall Wright effect) is a **random process**.

**Final Answer**: Genetic drift / Sewall Wright effect is a **random process**.
