Everyone knows that a unicorn is a mythical creature, but in her article, Carolyn Wilke mentions various ways to possibly create an animal with features identical to a unicorn. Albino horses and have white fur and light eyes, similar to that of a unicorn. An albino animal is the result of a mutation of one gene, and they do not make the pigment melanin which gives color to skin or fur. Creating a horn or rainbow color would be more difficult to produce on a horse, as they involve more genes and are more complex traits. Researcher Paul Knoepfler of the University of California mentions the use of CRISPR, a gene-editing tool that allows scientists to change an organism's DNA. He also mentions that it would be possible to make an animal that contains DNA from several different animals. Although it would be interesting to try these approaches to create a real unicorn, it may not be ethical. The animals created may have harmful reactions and important body processes could be affected. Also, this would not be natural and if a unicorn were to be created it may not be able to survive in the environment we live in.
