Final answer:
Natural selection and sexual selection do not always act in the same way to produce the highest fitness for males and females.
Step-by-step explanation:

In fact, they can have competing effects if the competition for mates is extreme. Natural selection primarily acts on females to produce the maximum number of offspring, while sexual selection primarily acts on males to help them outcompete rivals and attract mates.
