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.
Complete Heterochromia is rare in humans, but it is common in animals such as dogs and cats.
sectoral heterochromia is an autosomally dominant trait, meaning it is inherited from both your parents.
it depends on your point of view. Heterochromia is just a variation in eye color; not harmful.
my good sir, i am asking the exact same question...
3.5%
Actually, a decently sized amount of people have Central Heterochromia and neither is it very rare to have Sectoral Heterochromia. As for the numbers, I don't know the exact percent.
Nope
Heterochromia.
You can't, it's genetic.

"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.
