Question

What statement accurately desythe relationship between variations and fitness

Answer 1

Variations in traits can impact an organism's fitness in different ways. Some variations may confer advantages that increase an organism's fitness, while others may be harmful and decrease an organism's fitness. Natural selection acts upon these variations, favoring those that increase an organism's fitness and leading to their prevalence in the population over time. Therefore, variations play a crucial role in determining an organism's fitness and its ability to survive and reproduce in its environment.
