When human population groups are isolated, there is a higher level of A blood allele levels.The A blood allele is somewhat more common in the world today than the B blood allele, with 1 in 5 people have the A blood allele.Because of these differences, it is important to make sure that you know what blood type demographic you fit into in case there is a need for medical treatment. Two parents with B type blood can have a child that has O type blood. The child of two AB+ parents could have a child with AB blood, A blood, or B blood and it could either be positive or negative. Just because both of your parents have AB Positive blood, however, doesn’t actually mean that is what your blood type will be. Your blood type is determined by your parents. When a blood donation is necessary, having a blood type match and an ethnicity match can lower the risks of a rejection occurring.98% of sickle cell issues with human blood originate from people with an African-American or Black ethnicity.Asians are more likely to be B Positive and AB Positive than any other ethnic group.Caucasians are more likely to be A Positive than any other ethnic group.53% of Hispanics in the US are believed to have O Positive as their blood type, making them the largest ethnicity with this type of blood.Caucasians are 2x more likely to have a negative Rh factor compared to any other ethnic demographic and 14x more likely to have a negative blood type when compared to people from an Asian ethnicity. Negative Rh factors are the rarest types of blood.The most common blood type in humans from all ethnicities is O Positive.Ethnicity And How It Affects Blood Typing Based on these blood types, some basic demographic data can be collected about how our blood makes us the same, but also creates certain differences. AB blood is a universal donor for blood plasma. O blood is a universal donor for red blood cells and O Negative blood can be given to anyone, making it particularly valuable for blood donations. There are two types of universal donors when it comes to blood type. Each of these blood types is then assigned a positive (+) or negative (-) Rh value. There are 4 lettered blood types: A, B, AB, and O. The different typing is a reflection of the presence of antigens of the lack of them in certain combinations.
This is despite the fact that human blood is made from the same basic elements in every person. Humans have 8 basic blood types that are considered to be common.
