Blood type in Korea is not classified differently from ours, and is therefore divided into groups A, B, AB and 0. However, it is believed in Korea that blood type influences one's personality and therefore the way one behaves towards others, much like the zodiac signs.
Though it may ring weird to our ears, asking someone what their blood type is can be quite commonplace in Korean society. You can liken it to something similar to the Korean Zodiac, or the horoscopes in Western cultures.
The most important reason to know your blood type is in case of an emergency. If you are in a situation where you require a blood transfusion, you'll need compatible blood. An incompatible blood group can cause blood cells to clump—which can be fatal.
Many believe people with type O blood have an extroverted personality suited to collectivistic Korean culture and few character flaws, which may have arisen from the fact that type O blood is considered the “universal donor.”
In Korea, inquiring about each other's blood type is part of people's culture. Even though there's no official science behind it, a person's blood type is said to be connected to their personality. As such, this is usually considered a stepping-stone in forming an initial opinion of someone.
In Korea, Rh-negative is considered a rare blood type according to the Korean Red Cross standards, with an incidence of 0.4%; however, pregnancy can lead to several complications among Rh-negative women [10].
Referred to as “warriors,” people with type O blood are often viewed as natural leaders and are sometimes natural athletes, too. Outgoing, energetic, and optimistic, Os speak their minds without reservation while maintaining a friendly and easygoing demeanor.
Blood Type AB
But in reality, they are actually among the most caring, honest, and romantic of the blood types, and are generally the first to forgive.
Group O can donate red blood cells to anybody. It's the universal donor. Group AB can donate to other AB's but can receive from all others.
Asian: 0.1% AB-negative, 0.4% B-negative, and 0.5% A-negative.
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 type A is the oldest, and existed even before the human race evolved from our ancestors.
It starts from Korean culture which is classified as highly collectivistic. Predicting people's personalities based on their blood type and zodiac is particularly popular in Asian countries like Korea, Japan and China, which are all traditionally described as having collectivistic cultures.
BTS's Jin and Suga have type O blood, which accounts for 44% of the population. J-Hope, RM, Jimin, and Jungkook all have type A blood, the same as 42% of the population. V's blood type, however, is AB. Just 4% of the world's population has type AB blood.
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.
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.
Yes this is definitely possible.
Some of the most common traits of blood type A are as follows: Kind. Shy.
People with A blood type are sensitive, cooperative, emotional, passionate and clever. They are very patient, loyal and love peace and thus do not like to get into a fight with anyone.
According to popular belief, creativity is associated with people with blood type A.
[5] found a higher risk of COVID-19 among A and a lower risk among O blood types. Conversely, however, they estimated lower odds of mechanical ventilation for all non-O types, though the estimated odds ratios were not statistically significant at the 5% level for this outcome.
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.
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). Rhesus (Rh)-negative individuals were also less likely to be diagnosed with SARS-CoV-2 (ARR = 0.79; 95% CI, 0.73–0.85).
