Blood type is probably quite universal but medical conditions like congenital dermal melanocytotis are more reflective of inheritance. Another condition is sickle cell anaemia.
According to the CDC 1 in 333 white Americans carry the gene
Can a White Person Have Sickle Cell Anemia?
while its thought 1 in 20 white Americans have an African ancestor, having sickle cell almost guarantees a sub-Saharan ancestor. Another interesting characteristic is hair. My mother and brother have almost frizzy hair which is uncharacteristic of my extended family who have straight hair. Almost certainly a throwback to a distant Sub Saharan ancestor. I was watching a Youtube video of a New York woman whose father is Sicilian. From childhood her mother was unable to manage the frizz in her hair. After failing to find a hairdresser she stumbled onto a African American hairdresser who took one look and said your daughter has "black people's" hair. From early childhood she has been going to the same African American hairdresser.
