China blood phenotype is dominated by O type, but the r gene frequency is obviously lower than other countries.
In China, women often don't learn that they have a rare blood type until they become pregnant or plan to become pregnant. This was precisely the case for Wang, who discovered three years ago during a routine prepregnancy checkup that she has Rh negative blood — nicknamed “panda blood” because of its rarity.
Blood group O is the most common blood group.
Generally speaking, blood group O is the most common worldwide, but this varies according to ethnicity and geographical location. In Hong Kong, 40% of the population is type O, while types A and B are represented by about 26% of the population respectively. Interestingly, only 7% of Hong Kong's population is type AB.
In Japan, AB is the rarest blood type, while Type A is the most common one, followed by type O.
Blood groups in Australia
O positive - 40% O negative - 9% A positive - 31% A negative - 7%
The most common blood type in Australia is O positive and the least common is AB negative. The table below lists each of the blood types, including how common they are across the Australian population. This is the most common blood type. O- can be safely given to any patient, regardless of their blood type.
Africa. O+ is a strong blood group classification among African countries. Countries like Ghana, Libya, Congo and Egypt, have more individuals with O- blood types than AB+.
In the UK population, O is the most common blood group (48%). Around 7% of the population have O -ve blood, yet this special group accounts for around 13% of all hospital requests.
People with blood type O are said to be "universal donors" because their blood is compatible with all ABO blood types. It is also the most common blood type in populations around the world, including the USA (1) and Western Europe (2, 3).
Which blood group is most common? The most common blood group in India is O.
Approximately 45 percent of Caucasians are type O (positive or negative), but 51 percent of African-Americans and 57 percent of Hispanics are type O. Minority and diverse populations, therefore, play a critical role in meeting the constant need for blood.
Blood type A is the oldest, and existed even before the human race evolved from our ancestors.
In terms of demographics, around 34 percent of the Korean population are Type A and 28 percent are Type O, while 27 percent are Type B. Type AB accounts for the remaining 11 percent, according to the pollster. Scientifically, blood type differs according to the type of proteins in the blood.
The countries with the clearest majorities of a certain blood group are all for blood type O+, with 75 percent of Ecuador's population, followed by 70 percent of Peru and 63.3 percent of people in Zimbabwe.
Certain blood types are unique to specific racial and ethnic groups. Therefore, it is essential that donor diversity match patient diversity. For example, U-negative and Duffy-negative blood types are unique to the African American community.
As a result, its distribution varies among ethnic groups. Globally, the most common blood type is O, but the most common blood type of Europeans is A.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
Blood groups in Finland
In Finland, the most common blood group is A+ and the rarest is AB-. Blood groups in Finland are divided as follows: Rh D positive blood groups: A+ 35%, O+ 28%, B+ 16%, AB+ 7%
Blood group O donor blood is the most common blood group among Nigerian blood donors [69] and their red cells are commonly used as universal donor units for transfusion to A, B and AB recipient particularly in emergency situations.
The majority of the people in the world have the Rh+ blood type. However, it is more common in some regions. Native Americans and Australian Aborigines were very likely 99-100% Rh+ before they began interbreeding with people from other parts of the world.
In Aboriginal individuals we found that group O was more common than A in the 'Northern' NT, whereas there was similar distribution of the groups in 'Central Australia'. Conclusions: We found a significant difference in ABO and RhD blood groups between Aboriginal and non-Aboriginal individuals in the NT (P < 0.001).
Brothers and sisters don't always share the same blood type. The genotype of both parents plays a role in defining the blood type. For instance, children of parents with the genotypes AO and BO may have the blood types A, B, AB, or O. Thus, siblings do not necessarily have the same blood type.
