Which one of the following is NOT one of the secondary sex characteristics typical of males?
Secondary sex characteristic A peacock displays his long, colored feathers, an example of his secondary sex characteristics. Secondary sex characteristics are features that distinguish the two sexes of a species, but that are not directly part of the reproductive system. They are believed to be the product of sexual selection for traits which give an individual an advantage over its rivals in courtship and aggressive interactions.[citation needed] They are distinguished from the primary sex characteristics-- the sex organs-- which are directly necessary for reproduction to occur. Well-known secondary sex characteristics include manes of male lions and long feathers of male peacocks. Other dramatic examples include the tusks of male narwhals, enlarged proboscises in male elephant seals and proboscis monkeys, the bright facial and rump coloration of male mandrills, and horns in many goats and antelopes. Male birds and fish of many species have brighter coloration or other external ornaments. Differences in size between sexes are also considered secondary sexual characteristics. In humans, visible secondary sex characteristics include enlarged breasts of females and facial hair and adam's apple on males.
