Are Zebras Born With Their Stripes?

Zebras are recognizable to anyone as the black and white striped animal. However people wonder are those stripes there at birth or are they something that develops later. Zebra foals are born with stripes yes, but with black and white stripes, no. The zebra foals are born with brown and white stripes. As they mature the brown darkens into a black. No two zebras have the same stripe pattern, this makes it so that they can be recognized easier. If a foal were born with out stripes it would be harder for the mare to identify her offspring. Also zebras gestate for about a year. This means that maybe the stripes had time to develop during the long pregnancy. We do know that zebra foals come into this world already donning their stripes.
