Therefore we see that the most common blood group in India is O positive. The second most prevalent blood group in India is B positive.
The most common blood group among the Indian population is O+ that is present in approximately 35% of the population.
Asian: 39% O-positive, 27% A-positive, and 25% B-positive.
All major ABO blood alleles are found in most populations worldwide, whereas the majority of Native Americans are nearly exclusively in the O group. O allele molecular characterization could aid in elucidating the possible causes of group O predominance in Native American populations.
Type O is particularly high in frequency among the indigenous populations of Central and South America, where it approaches 100%. It also is relatively high among Australian Aborigines and in Western Europe (especially in populations with Celtic ancestors).
Results: The Aboriginal and non-Aboriginal populations had significantly different ABO and RhD distributions (P < 0.001). For Aboriginal individuals, 955/1686 (56.6%) were group O and 669/1686 (39.7%) were group A. In non-Aboriginal individuals, 1201/2657 (45.2%) were group O and 986/2657 (37.1%) were group A.
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.
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. Types O negative and O positive are in high demand.
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).
Based on the primary races hypothesis, it was thought that in the three major races of man, blood groups A in Europe, B in Asian, and finally O in South America have been emerged and gradually due to the migration and mixing of the races, became the present situation.
The ranking of ABO blood groups phenotypic distribution in China is O > A > B > AB. The proportions of A, B, O and AB type in China population are 28.72%, 28.17%, 34.20%, and 8.91%, respectively.
What are the rarest and most common blood types? In Japan, AB is the rarest blood type, while Type A is the most common one, followed by type O.
Heterogeneity between countries has become apparent and has led to the conclusion that the European Roma are composed of two different populations, characterised respectively by a high and a low frequency of blood group B [23], or defined as East and West European Roma, with the former closely related to Indian ...
The most common blood group for people living in the UK (44%) is the O group blood, followed by the A blood group (42%). This means these blood groups are the most commonly requested by hospitals for patients in need. The least common blood groups are B (10%) and AB (4%) blood groups.
The rarest blood types are: B negative(B -ve), which is found in 1.5 percent of the total population. AB negative(AB -ve), which is found in 0.6 percent of the total population. AB positive(AB +ve), which is found in 3.4 percent of the total population.
Rh-null or golden blood
When a person's blood lacks all 61 possible antigens, they are said to be Rh-null. Because Rh-null lacks all possible antigens, it can be donated to people who have blood types that are very different from the main eight.
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.
Interestingly, a high proportion of centenarians in our cohort (70%) were of O blood type, which has been found in several studies and meta-analyses to protect from cardiovascular diseases and cancers (e.g., pancreatic and gastric cancers)17.
Life Span. Chances are higher you'll live longer if you have type O blood. Experts think your lowered risk of disease in your heart and blood vessels (cardiovascular disease) may be one reason for this.
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%
A woman's blood group could influence her chances of getting pregnant, scientists have found. Those with blood type O may struggle to conceive due to a lower egg count and poorer egg quality, while those with blood group A seem to be more fertile.
(7,8) Their high rate of blood group O suggests that the Amerindians and Eskimos are directly descended from Cro-Magnon ancestors, probably Mongolians, who migrated around 15,000 B.C. to the Americas.
A baby may have the blood type and Rh factor of either parent, or a combination of both parents. Rh factors follow a common pattern of genetic inheritance. The Rh-positive gene is dominant (stronger) and even when paired with an Rh-negative gene, the positive gene takes over.
Rh incompatibility occurs when the mother's blood type is Rh negative and her fetus' blood type is Rh positive.
Blood type may impact stroke risk, too. A 2022 study published in the medical journal Neurology reviewed 48 studies of 17,000 stroke patients and found that people with type A were 16 percent more likely to have an early stroke than people with other blood types, and those with type O were 12 percent less likely.
