![### Genetic Variations in Natural Populations
Genetic variations in natural populations develop due to:
**Select one:**
- A. random mutations of the DNA.
- B. changes in diet.
- C. environmental catastrophes.
- D. changes in the environment.
- E. individual activities.
### Explanation:
Understanding the mechanisms behind genetic variations is crucial for studying population genetics. These variations are essential for the adaptation and survival of species in changing environments. The options provided consider different potential factors, but it is widely accepted that random mutations of the DNA are a primary source of genetic variation. Other factors like environmental influences, diet, and personal activities could contribute indirectly by affecting mutation rates or selection pressures.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff5bd1a27-e559-4abd-b158-898799f60d66%2Fc07e52f0-8aab-4ed8-a777-92826f5f2dba%2F9r9qum_processed.jpeg&w=3840&q=75)
