Can 2 brown eyes make blue?

The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby.

Can heterochromia cause blindness?

A: While it is rare and quite uncommon, heterochromia can cause blindness when coupled with pre-existing conditions such as inflammation of the eye. As a side effect of the disease itself, blindness is not commonly reported in people who have heterochromia.

Does heterochromia run in families?

What are the 3 types of heterochromia?

Types Of Heterochromia

The three categories are complete, segmental, and central heterochromia. Complete heterochromia, also called heterochromia iridum, occurs when the two irises are different colors.

What is the rarest heterochromia?

How rare is central heterochromia? Complete heterochromia is definitely rare — fewer than 200,000 Americans have the condition, according to the National Institutes of Health. That's only about six out of every 10,000 people.
