Quizplus · Accepted Answer

Primary sexual characteristics are those that directly involve the reproductive system, such as the presence of testicles in males. Manes in male lions and antlers in male elk are examples of secondary sexual characteristics, which are physical traits that enhance mating success but do not directly involve reproduction. Male birds having more colorful feathers than females are also an example of a secondary sexual characteristic.
