A genetic trait with fitness of more than one will

Options

A. Remain insignificant in a population
B. Spread rapidly in a population
C. Spread slowly in population
D. Get eliminated.

Answer

To solve the question "A genetic trait with fitness of more than one will:", we need to analyze the implications of a genetic trait having a fitness greater than one in the context of evolutionary biology.

### Step-by-Step Solution:

1. **Understanding Fitness**:
- Fitness in evolutionary terms refers to the ability of an organism to survive and reproduce in its environment. A fitness value greater than one indicates that the trait enhances the organism's reproductive success compared to others in the population.

**Hint**: Remember that fitness is a measure of reproductive success relative to others.

2. **Implications of High Fitness**:
- A genetic trait with a fitness greater than one suggests that individuals possessing this trait are more likely to survive and reproduce than those without it. This means that the trait confers some advantage.

**Hint**: Consider how advantageous traits affect survival and reproduction.

3. **Natural Selection**:
- Traits that confer higher fitness are subject to natural selection. Over time, these traits become more common in the population as individuals with the advantageous traits reproduce more successfully.

**Hint**: Think about the process of natural selection and how it favors certain traits.

4. **Population Dynamics**:
- Since the trait is advantageous, it will spread rapidly through the population. This is because individuals with the trait will have more offspring, and those offspring will inherit the trait, leading to an increase in its frequency.

**Hint**: Consider how advantageous traits proliferate in a population over generations.

5. **Conclusion**:
- Therefore, the correct answer to the question is that a genetic trait with fitness of more than one will "spread rapidly" through the population.

### Final Answer:
A genetic trait with fitness of more than one will spread rapidly through the population.
