What causes animals to have stripes?

The patterns depend on a chemical process called a reaction-diffusion model, first hypothesised by Alan Turing in the 1950s. If the embryo is very small, no pattern forms. Shape also plays a role: if part of the embryo of a potentially spotted animal is elongated, that part can become striped.

What animal got stripes?

Zebras, together with horses and asses, are members of the Equus genus. The three living species of zebras that roam eastern and southern Africa with their coat of dark hair broken by stripes of white, unpigmented hair, are the only striped equids.

Why do zebrafish have black and white stripes?

Kondo’s lab works on understanding the black and white stripes presented on zebrafish, a tropical freshwater fish, which is native to the Himalayan region. They discovered that zebrafish skin patterns are made up of a light type of cell (xanthophore) and a dark type of cell (melanophore) that interact with each other.

Why does an animal have a certain skin pattern?

Biologists may be able to tell you why an animal has a certain pattern. For example, it may have evolved its skin pattern for mating purposes, as a warning sign, or for defence purposes. However, we are still in the dark when it comes to how the patterns are produced.
