It is a recessive gene, which means that you need to recieve to copies of it to have blue eyes, so basically one from each of your parents. The parents might not have blue eyes themselves, they just need to have a copy of the gene. If both parents have brown eyes, the chances of getting blue eyes are very low. If both parents have blue eyes, then all children will have blue eyes. So, to conclude, we still don't know if the dad had blue eyes or not but Kwon inherited his from them both. It was team work.
