The tendency of population to remain in genetic equilibrium may be disturbed by

Options

A. Lack of migration
B. Lack of mutations
C. Lack of random mating
D. Random mating.

Answer

To solve the question regarding the disturbance of genetic equilibrium in a population, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Genetic Equilibrium**:
- Genetic equilibrium refers to a state where the allele frequencies in a population remain constant over generations. This concept is crucial in population genetics and is described by the Hardy-Weinberg principle.

2. **Identifying Factors Affecting Genetic Equilibrium**:
- According to the Hardy-Weinberg principle, several factors can disturb genetic equilibrium. These include:
- Mutations
- Natural selection
- Genetic drift
- Migration (gene flow)
- Non-random mating

3. **Focusing on Non-Random Mating**:
- Among the factors listed, non-random mating is particularly significant. When individuals in a population do not mate randomly, it can lead to changes in allele frequencies, thereby disturbing genetic equilibrium.

4. **Conclusion**:
- The question specifically asks what can disturb the tendency of a population to remain in genetic equilibrium. The most relevant factor here is the lack of random mating.

5. **Final Answer**:
- Therefore, the tendency of a population to remain in genetic equilibrium may be disturbed by the lack of random mating. The correct answer is option C: lack of random mating.
