Genetics is a weird thing. Both my sister and I have blue eyes. My mom had blue eyes & was Polish & Russian. My father is Sicilian with brown eyes & my grandmother couldn't name 1 relative going back to 1910 who had blue eyes. Obviously, there is a recessive blue gene on my father's side.
A friend in high school was blonde, blue-eyed with fair-skin and on the heavy side. Her sister was olive with brown eyes with a slender frame. They looked nothing alike but were sisters.
With Angelo being French, Italian and Algerian and Regina being only half puerto rican, Bay is possible. I mean ... I inherited my Sicilian waif-genes of my great-grandmother last seen 3 generations before me!
