Unexplained events and mysteries

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.

Blood type O is near universal among native first native peoples in North America A and B thousands or millions of year old, AB at most no more than two thousand years old, No old grave sites in Europe had AB blood very rare even now only 1% of population in Europe. The probability of an European like myself having AB blood from both parents is 1 in 10,000. Finding my mothers dad, had a distant relative whom married my grand mothers distant relative explains this One family carriers of AB.

Fair enough, could this AB blood type be inherited from an unknown native American ancestor perhaps?
