Answer 2

Male and female giraffe are almost impossible to tell apart, except for the fact that males are bigger than females. The distinct horns (technically called ossicones) on a giraffe's head differ between sexes. Female ossicones are usually covered in hair, while the male ossicones are bald on top. To establish dominance, males engage in a behavior called necking. Males will swing their necks and use their horns to hit another male for access to fertile females. With increased impact, the hairs on males' ossicones wear down. Because females rarely fight, their hairs remain in tact.
