Is heterochromia genetic?


Hello. What is the exact cause of heterochromia? Is it a genetic mutation? If I have heterochromia, can my children inherit it?


This is an awesome question!
Heterochromia is usually determined by the concentration of melanin. Sometimes it can be inherited or caused by genetic factors and enviromental factors (disease or injury).
The main cause of heterochromia is a mutation of the genes that determine melanine distribution.
If you have heterochromia is it possible for your child to inherit it, but the chances are very small, depending on the factors that caused you to have it in the first place.
