How rare is complete heterochromia?

How many people have heterochromia?

Complete Heterochromia is rare in humans, but it is common in animals such as dogs and cats.

Can central heterochromia eventually expand to sectoral or complete heterochromia?

my good sir, i am asking the exact same question...

Can Heterochromia be passed on to children?

Heterochromia is a genetic mutation that cannot be passed down to children. It occurs as a defect in meiosis, and it produces an extra gene for eye colour. Alas, there is a greater chance that the child of a person with heterochromia will also get heterochromia, because there is a better chance of the gene mutating. But still, the chance of heterochromia is rare nonetheless.

Do I have Central Heterochromia?

"Hazel" eye coloring is sometimes caused by central heterochromia. It's still not particularly prevalent in general, but it's not as rare as one might think.

How much of the world's population has heterochromia?

How rare is sectoral heterochromia?

I would have to completely disagree as well. Central Heterochromia is so common it's not even funny. I have Sectoral (or partial) heterochromia and i have yet to see anyones eyes (in person) that look like mine. I have one full blue eye, and the other eye is brown with a chunk of blue in it.) So to answer your question- Central Heterochromia= definitely common. Have you seen many people walking around with two completely different colored eyes? I have to see even one, but think this - central heterochromia is even rare among that! It signifies abnormally levels of toxin in the body in most cases, but sometimes it's genetic. (I have central heterochromia) I have central heterochromi(genetic)I have three colors actuall. brown in the cener and green outter. but there is also a even darker green ring on the very outside edge of my iris. my dad has full heterochromia one eye is green and one is brown. His green eye also has central heterochromia. newtest3 ---- Hello! I would have to disagree with them. Central Heterochromia doesn't seem to be as rare as Partial or Full Heterochromia. I myself have Central Heterochromia and know a few other people who do as well, whereas I don't know anyone with Partial or Full. And from what I understand of the research I've done, Partial is even rarer than Full. In the people I know with Central Heterochromia, most of them are usually classified as having "hazel" eyes because they have those different colored rings. Now, that's not the case for all people with hazel eyes, but it's very common for them to be misclassified. So in terms of rarity, you have to think how many people in the world have hazel eyes? ~ I guess I'm the odd one then... I have Sectoral and Central heterochromia... My eyes are normally green, but when you look at the, the top half of both of them is brown. They also have a dark grey ring around the outside of them, as I just recently discovered. The odd thing about that, is that my mom had blue/grey-ish eyes, and my dad has hazel ones. Neither my parents, nor their parents have brown eyes.

What form of heterochromia is the most rare?

A total inability to distinguish colors (achromatopsia) is exceedingly rare. These affected individuals view the world in shades of gray. They frequently have poor visual acuity and are extremely sensitive to light (photophobia)

Is sectoral heterochromia inherited?

sectoral heterochromia is an autosomally dominant trait, meaning it is inherited from both your parents.

Is heterochromia bad or good?

it depends on your point of view. Heterochromia is just a variation in eye color; not harmful.

What percentage of dogs have heterochromia?

3.5%

Is there a word for someone who is born with different colored eyes?

If you have different coloured eyes it is called heterochromia but is nothing to be worried about. I'm not just saying that because I am but you know. You should be proud of it because it is to rareand special to be taken the mick out of! You could either have: 1. Blue and Green eyes 2. Blue and Brown eyes 3. Brown and Green eyes (Like Me) So their you have it nothing to be ashamed of!
