I need help to know why my eyes are the way they are. My mom said I had a twin. During the pregnancy, we had a blood fusion or something like that. The twin then ended up not being born but our chromosomes mixed. But I have a cousin who says it might be some Waardenburg syndrome. He says that because I have two eye colors and hair in between my eyebrows. Can someone tell me if it is one of those two reasons or if it's something else. If it helps, my mom also says that the twin thing is why my face turns half red when I exercise.
