Is Central heterochromia a dominant trait?

Risk Factors for Heterochromia

Genetic heterochromia is an autosomal dominant condition. This means the genetic abnormality must be dominant in just one parent to pass the condition on to a child. Each child of a parent with the dominant trait for heterochromia has a 50% chance of developing the condition.

What kind of trauma causes heterochromia?

People who weren’t born with heterochromia might still develop it, as it can also be caused by trauma (due to injury or surgery) or disease (such as diabetes, eye tumors, or glaucoma).

What is heterochromia caused by?
