some animals that look like they exhibit codominance actually don't. For example, the zebra obtains its black-and-white stripe pattern from a series of genes that initiate the production of a dark pigment called melanin on specific parts of its body. Different zebras can have different patterns of stripes as dictated by their genetic code. For example, the plains zebra has wide stripes, while the Grevy's zebra has narrow stripes. What are some examples of striped and spotted animals that are genetically encoded to have these designs?

The biodiversity of the islands has decreased.

Explanation: Galapagos Islands is located in an island in Equador, it is at this island that Charles Darwin carried out his biodiversity experiment. The island is known to contain a wide range of diverse species that are unique to the Galapagos Islands.

The biodiversity of the Island is been threatened in recent times due to destructive activities of Humans,people are introducing Alien species like the Goats now introduced into the farm by some farmers years ago, the dumping of refuse,the high rate of buildings coming up around the island and the influx of Tourists all these are making the Inherent species to find the environment unattractive any longer hence, they are going into extinction.
