My partner and i have a 9mo, so i know his eye colour could still change. him and i have hazel, our son had blue, and only one grandparent has blue eyes. what’s the likelihood of different eye colours for him?
thank you!

The gene that gives the iris the colour brown is a dominant gene. blue is recessive gene. This means the likelihood of your son to have blue eyes are pretty low. But it is not impossible. With the your information about your grandparent, it is likely a 85% chance for being brown.
The iris can also become Green. I would say there is equally big chance the eyes become green as the chance of them becomming blue.
