What statement accurately describes the relationship between variations and fitness

Answer 1

Variations in traits can affect an organism's fitness, or ability to survive and reproduce in a particular environment. Some variations may provide an advantage in certain conditions and increase an organism's fitness, while others may decrease fitness. Natural selection acts on these variations to weed out traits that are detrimental to fitness and promote those that enhance it. Therefore, the relationship between variations and fitness is that variations can influence an organism's fitness through natural selection.
