There are families that have a certain genetic marker of the eyes, looking more or less like the opposite of the epicanthic fold of Asian eyes. I have seen it in some Native Americans and some people of French descent.
If you look at the outer and upper corners of this Native American girl’s eyes, you will see it.
The royal family also has this. It is not common, and is a marker in my (native american) family. The older one gets, the more pronounced it becomes, and it tends to droop in the upper corners of the eyes. What is this called?
