Caucasian: 1% AB-negative, 2% B-negative, and 3% AB-positive.
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.
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.
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).
Irish Blood Group Type Frequency Distribution
Blood group O Positive is the most common group in Ireland while AB negative is the least common.
The second most common blood type is A positive which occurs in "33% of Caucasian, 24% of African American, 27% of Asian and 29% of Latino American" populations," says the Red Cross.
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.
China blood phenotype is dominated by O type, but the r gene frequency is obviously lower than other countries.
The most common blood types differ somewhat between Poland and Ireland. Here, 47% of people are O+, whereas in Poland 31% of the population are O+. The combined percentage of people in Ireland who are A+ and B+ is 35%; in Poland, it's 47%. There are also differences between the two countries' blood-donation procedures.
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 ...
Taken together, the authors concluded that type O and Rh-negative blood groups may be protective against SARS-CoV-2 infection and illness.
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.
Type O positive blood is critical in trauma care. Those with O positive blood can only receive transfusions from O positive or O negative blood types. Type O positive blood is one of the first to run out during a shortage due to its high demand.
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.
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.
You inherit a gene from each parent so your blood type may not be the same as your parents. For example: If you inherit an A from one parent and an O or A gene from another parent, you will have type A blood. Type B from one parent and type O or another type B gene from the other parent will give you type B blood.
Having a non-O blood group is associated with an increased risk of death, particularly from cardiovascular disease (such as ischemic heart disease and stroke), according to research published in open access journal BMC Medicine.
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.
Can your blood type change? Usually, you'll have the same blood type all of your life. In rare cases, however, blood types can change. The change usually relates to unique circumstances, such as having a bone marrow transplant or getting certain types of leukemia or infections.
