China blood phenotype is dominated by O type, but the r gene frequency is obviously lower than other countries.
Asian: 39% O-positive, 27% A-positive, and 25% B-positive.
The ABO blood group system is the most important in transfusion medicine. O blood group is common in Chinese Han people, but the distribution of various O alleles is unknown.
O positive: African-American: 47% Asian: 39% Caucasian: 37%
O-negative blood type is most common in the U.S. among Caucasian adults, at around eight percent of the Caucasian population, while only around one percent of the Asian population has O-negative blood type.
Blood groups in Australia
According to Australian Red Cross Lifeblood, the percentage of blood group frequency in Australia is: O positive - 40% O negative - 9% A positive - 31%
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.
The gene for type O is 'recessive', because if you have one gene for O and one for A, then you still end up with A antigens on your cell membranes, and the same goes for O and B. In order to be group O, you need both parent cells to be O. But group O is still more common simply because it is the ancestral form.
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).
38% of the population has O positive blood, making it the most common blood type. O positive red blood cells are not universally compatible to all types, but they are compatible to any red blood cells that are positive (A+, B+, O+, AB+).
Type O. Being 开朗 (kāi lǎng) outgoing, 自信 (zì xìn) confident, and 善良 (shàn liáng) kind – Type Os are natural born leaders who are true romantics at heart.
No less than two-thirds of people in several East Asian countries and areas, such as Japan, South Korea, and Taiwan, believe in the association between blood types and personality.
Meanwhile, type A blood was the most prominent in Korea, accounting for roughly 34 percent of the population, followed by type O (28 percent), type B (27 percent), and type AB (11 percent), according to Gallup Korea.
In Japan, AB is the rarest blood type, while Type A is the most common one, followed by type O.
Blood type A is the oldest, and existed even before the human race evolved from our ancestors.
Which blood group is most common? The most common blood group in India is O.
Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there's a limited supply of the exact matching blood type. That's because type O negative blood cells don't have antibodies to A, B or Rh antigens.
Dana Devine, shows that people with blood groups A or AB are more likely to have a severe COVID infection than people with blood groups B or O. The study looked at 95 patients critically ill with the SARS-CoV-2 virus in the intensive care units (ICUs) of two major Vancouver hospitals.
The authors found that individuals with type O blood were less likely to contract SARS-CoV-2 compared with non–type O blood groups (ARR = 0.88; 95% confidence interval [CI], 0.84–0.92).
Theoretically yes, but it would be extremely rare. Two O parents will get an O child nearly all of the time. But as with anything in biology, there are occasional exceptions to this rule. New mutations -- or changes in the DNA -- are theoretically one way these kinds of uncommon scenarios can happen.
While blood group O positive has some advantages, it also has some disadvantages that people should be aware of. People with blood group O positive may be at a higher risk of developing certain health conditions, including heart disease, stomach ulcers, blood clotting disorders, high cholesterol, and pancreatic cancer.
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.
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. Why is this type in such demand? It's down to antigens, or rather lack of them.
