Have You Ever Considered A Disease Cute.docx

Have you ever considered a disease cute? Well there's this one that happens genetically and it just so happens to be adorable. It occurs in animals, and it affects their eyes, hair/fur, and even their skin! This is called Heterochromia. (yes it's a big word) Heterochromia happens in humans too. This happens to both humans and animals when there is a lack of pigment in the melanin in a cell. To animals it can change their eye color, skin color, and hair and fur color. With heterochromia, animals' skin is affected. There is some animals with heterochromia in their skin because of the lack of melanin in the skin cells of the animals. This can occur on any part of the animal, including the back, hands, face, or chest. Skin heterochromia affects the color of skin, meaning that there can be a dog with pale skin and spots of black. Animal heterochromia can be affected through parental genes. This means that this disease can be genetic. Also with heterochromia, an animals eye color can be affected. There are two types of eye heterochromia with animals. There is complete and Partial. Complete Heterochromia is where one eye color of an animal is completely different from the other. For example, on eye can be green and the other can be blue. Partial heterochromia is where there is multiple colors in one eye. With animals, partial heterochromia happens the most in dogs and cats. Eye heterochromia is genetic because of the passing down of genes that sometimes lack melanin. Heterochromia also occurs in the hair/fur of the animal. This happens because of a disorder in pigmentation through parental genes. Heterochromia happens in hairs when an animals hair or fur can become any shade darker or lighter on the body. This type of heterochrom is mt`0-ost common in cats, and only about 3.5% of dogs have this genetic mutation. The coat of the animal can be affected with white spots all around the body.

To conclude, heterochromia can affect animals genetically through their skin, eyes, and fur. This genetic disease happens when there is a lack of melanin in certain genes. Heterochromia doesn’t cause any major disruptions in an organism, but it is noticeable. Heterochromia can change one of the animals' eye color completely or partially. This disease happens throughout an organism, and it's completely harmless!
