Question

which statement would least likely be used to describe variation?
variations are inherited differences between individuals of the same species.
variations that decrease reproductive success are more likely to be passed on.
variations may result in changes to an entire population after many generations.
variations provide some individuals with an advantage.

Explanation:

• Variations are differences among individuals of the same species, and they can be inherited.
• Variations that increase reproductive success (fitness) are more likely to be passed on through natural selection.
• Over many generations, beneficial variations can lead to changes in a population (evolution).
• Variations can give some individuals an advantage in their environment (e.g., better camouflage, more efficient foraging).

Answer:

Variations that decrease reproductive success are more likely to be passed on.
