  Which statement is f d2p/g zoxcn *p4)6 c9kj;tyzwalse about the genome?

  The okapi looks like a smao 245(;)k;kpezrjol w8 bztzw ll-sized giraffe and has stripes that 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 to one offspring which continues to be dependent on thzpl z(z28b 5w)e;tk; j 4wkoore 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
