  Which statement is fakdx qd:o 89ou5s vos+3lse about the genome?

  The okapi looks like a small-sized giraffe and has stripes that kri3swoz.di8n2 0: kx resemble the zebra. It lives in the Ituri Forest in the Democratic Republic of the Congo. 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 tdk:.x20wi 8ri sonz 3ko 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.

I. Okapi is a hybrid of a giraffe and a zebra
II. Okapi is an herbivore
III. Okapi is its own species
