So far, scientists have only found out a certain part of this special color of Zebra - some interesting facts. However there are many who wonder whether, in fact, the zebra is white with black stripes or black and white stripes?

Why do zebras have stripes?
First, this special color of Zebra has a great effect to help them survive the harsh conditions in Africa. Alternating black and white colors to help them make up to 70% of sun heat absorption into the body. The layout of the zebra stripes on the body is also very unique, it generates signals for each zebra like human fingerprints. As for it's zebra stripes at the shoulders or neck, helping them to recognize the members of the board.

Contrary to popular belief, the brightly colored zebra can attract predators such as lions or hyenas. But in fact this is the black and white striped zebra to help divert these species. When the zebras standing gathers together, the scientists said that with the number of large black and white striped can fool the other carnivores.

Thus we can see the black and white stripes of the zebra have a great effect, helping them survive the harsh conditions and against predators. But the truth, the zebra is white with black stripes or black and white stripes? If you just rely on our visual inspection is difficult to answer this, because the black and white stripes are evenly distributed over the entire body of them no plants for kids...

To answer this question, we must learn more about the pigmented cells under their skin. Melanocyte cells subcutaneously role feather pigment production. For zebras, too, this melanocyte cells their color decisions. Based on the analysis of pigment cells in the embryonic stages of the zebra, the scientists were able to find the answers.

Lisa Smith was the study of large mammals at Zoo Atlanta has conducted his research on species of zebra. In this study, Lisa discovered black zebra activated as a result of pigment by melanocytes cells, while white is the result of the inhibition of pigmentation. That also means that black is the main color of the zebra species, and the white stripes are the result of the inhibition of melanocyte cells, causing them to not create black and white stripes thereby.
