Question

Genetic variation is beneficial because it won can increase mutation 2. Requires only this born of fight generation 3 can help a species better adapt to environmental changes. Four protects individuals in a species equally against disease

Answer 1

Genetic variation is crucial for the survival and adaptability of species for several reasons, particularly as it relates to evolution and natural selection.

Among the options you provided, the most accurate statement regarding the benefits of genetic variation is:

**3. Can help a species better adapt to environmental changes.**

Here's a brief explanation for each option:

1. **Can increase mutation**: While genetic variation can arise from mutations, it doesn't directly "increase" mutation. Instead, it is the result of mutations that lead to diversity in a population.

2. **Requires only this born of fight generation**: This statement is unclear and does not accurately reflect how genetic variation works; variations can arise from many generations and mechanisms, including mutation, sexual reproduction, and gene flow.

3. **Can help a species better adapt to environmental changes**: This is true. Higher genetic variation within a population increases the chances that some individuals will possess traits suited for survival in changing conditions, enhancing the population's overall adaptability.

4. **Protects individuals in a species equally against disease**: This is not accurate. While genetic variation can allow some individuals to develop resistance to certain diseases, it does not protect all individuals equally. In fact, if a population has low genetic diversity, a disease can potentially wipe out large portions of it.

In summary, genetic variation enhances a species' ability to adapt and survive in changing environments, making statement 3 the most relevant and accurate.
