What statement accurately describes the relationship between variations and fitness?
What statement accurately describes the relationship between variations and fitness?
The relationship between variations and fitness is that variations in a population can affect an individual's ability to survive and reproduce in a given environment, leading to differences in fitness among individuals and potentially resulting in natural selection and evolution of the population over time. Individuals with advantageous variations that increase their fitness have a better chance of surviving, reproducing, and passing their beneficial traits to their offspring, while individuals with less advantageous variations may struggle to survive or reproduce. Therefore, variations play a crucial role in determining an individual's fitness and the overall genetic makeup of a population.
