How many people have orange eyes?

Answer 1

Different colored irises (a condition known as heterochromia iridium) is caused by a lack of melanin in one of the eyes. It is thought to result due to an alteration in one of the genes that controls eye color, and is relatively rare in humans. It can be an inherited trait, but can also be caused by trauma and certain medications.
Eye color is determined by the amount of melanin, a dark brown pigment, present in your irises. Blue eyes are due to a lack of melanin, while brown eyes indicate melanin-rich irises. Thus, people with darker hair and skin have higher levels of melanin and tend to have brown eyes, while people with lighter hair and skin have lower levels of melanin and usually have lighter colored eyes. This is also why many babies are born with blue eyes. Their eyes change color later as they begin to produce more melanin.

When an individual has different amounts of melanin in each of their irises, their eyes are different colors. Heterochromia iridium (the scientific name for two different color eyes in the same individual) is relatively rare in humans but common in some animals, such as horses, cats, and certain species of dogs. A variation on the condition is heterochromia iridis, in which an individual has a variety of colors within one iris.

Heterochromia iridium is thought to result from an alteration to one of the genes that controls eye color. This can be an inherited trait, although trauma and certain medications may result in increased or decreased pigmentation in one of the irises. Certain medical syndromes, such as Waardenburg syndrome, may also cause someone to have two different colored eyes.

Some people with this condition wear colored contact lenses so their irises match, while others take pride in their striking appearance.

Answer 2

Someone answered this wrong on Yahoo Answers, so here's how you actually do it. Since there are other factors other than genes that can determine having two different colored eyes, such as trauma to the eye, mutations, etc, there's no way of knowing. I don't know how many people are in the whole have two different colored eyes. There's also no real way of knowing the probability of your child, say, having two different colored eyes unless you know if you are a carrier of the recessive gene (e=two different colors) as well as whether or not your significant carries the recessive gene. The dominant gene is same colored eyes (E). Theoretically...

If both of you display the dominant gene of having the same colored eyes but are both carriers of the recessive gene, you have a 1 in 4 chance of having a child with two different colored eyes:

If one of you has same colored eyes and is not a carrier, and one of you has two different colored eyes, you have no chance of having a child with two different colored eyes:

0/4 =0%

If both of you have same colored eyes, and only one of you is a carrier of the recessive gene, you have no chance of having a child with two different colored eyes:

If one of you has the same colored eyes but is a carrier of the recessive gene, and one of you has different colored eyes, you have a 1 in 2 chance of having a child with different colored eyes:

Waardenburg syndrome can cause different colored eyes and its a dominant gene.

Answer 3

Red eyes are very uncommon, and less than 1% of people have them. They are mainly found in albinos, but nonalbinos have been known to have red eyes.

Answer 4

It's hard to get an exact count. I've been looking all over also because I have two different colored eyes, ;)

Answer 5

Brown, blue, gray, green, amber, hazel. Albinos have red eyes.

Answer 6

there may be a few people with orange eyes but I am not certain because its very rare to be born with orange eyes

Answer 7

about 80 percent have brown eyes

Answer 8

90% of the world have brown or hazel eyes
