Rhinoceros is an animal that starts with RH. Additional animals include rhesus monkey and rhea.
Approximately 90% of African Americans are Rh-positive, which is similar to the general population's Rh-positive rate. The Rh factor is a specific protein found on the surface of red blood cells, and its prevalence can vary among different ethnic groups. This means that a significant majority of African Americans have the Rh-positive blood type.
Approximately 4-8% of the African American population in the US is Rh-negative.
The rh blood factor was first observed in Rhesus monkeys
Rhesus positive (Rh+) refers to the presence of the Rh factor, a specific protein on the surface of red blood cells. Individuals with this protein are considered Rh positive, while those without it are Rh negative (Rh-). The Rh factor is important in blood transfusions and pregnancy, as incompatibility between Rh+ and Rh- blood types can lead to serious health issues. Approximately 85% of people of European descent and 95% of people of African descent are Rh positive.
I think Rh is not a blood group. Rh stands for a factor and derived its name from factor found in the blood of Rhesus monkey.
