  Which statement is fala w2xxsq- ri(+se about the genome?

  The okapi looks like a small-sized giraffe anne9x)gv4 p i2xd has stripes that resemble the zebra. It lives in the Ituri Forest in the Democratic Republic of the Co9v4n xg2pex)i ngo. Okapis eat the leaves and buds of trees they can reach. They also graze on grass and ferns and eat fruit. Okapis tend to be solitary animals and the mother gives birth to one offspring which continues to be dependent on the mother’s milk for six months. When they are four to five years old, they are mature and can breed, but only with other okapis.

Which of the following statements is applicable to the okapi?
I. Okapi is a hybrid of a giraffe and a zebra
II. Okapi is an herbivore
III. Okapi is its own species
