Complete Heterochromia is rare in humans, but it is common in animals such as dogs and cats.
Heterochromia is a condition where one eye's iris is a different color than the other eye's iris or one part of an eye's iris is a different color than the rest of the same eye's iris. Heterochromia is more common in dogs and cats than it is in humans. It can be acquired genetically or by an injury or inflammation.
Probably not. In many breeds it is considered a flaw so the dog may be less expensive.
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.
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...
The percentage of families with dogs in the world is 73%.
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.
