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.
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.
Blood Type A: Central and Eastern Europe
Type A is common in Central and Eastern Europe. In countries such as Austria, Denmark, Norway, and Switzerland, about 45-50% of the population have this blood type, whereas about 40% of Poles and Ukrainians do so.
The 10 countries with the highest prevalence of type A+ blood: Armenia (46.3%) Norway (41.6%) Malta (41.0%)
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.
A+ is a powerful blood type because it is the second most common blood type. Since 36% of the population is A+ it is among the blood types transfused most often. The most powerful part of A+ blood can be found in the platelets. Platelets can be donated as often as every seven days and up to 24 times a year.
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.
Because blood types are genetic, they are inherited from the parents, blood types have different racial and ethnic differences. The majority of people in the world and across various ethnicities have Rh+ blood type. Subsaharan African populations have a 97-99% Rh+ factor. East Asian communities have 93-97% Rh+ blood.
Blood group reference distribution for the German population is given as: 0: 41%; A: 43%; B: 11%; AB: 5%; Rhesus positive: 85%; Rhesus negative: 15%.
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).
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).
Type A is the most ancient blood type and has been found in hominids – or pre-humans. Scientists can use DNA from some blood cells found in fossils to help figure this out. Type O probably originated next, about 5 million years ago. Scientists are still trying to pinpoint when exactly each blood type evolved.
Which blood group is most common? The most common blood group in India is O.
While over 70 percent of Mongolia's population have A and B positive types, 0.6 percent has rare blood type – the Rh negative. People with negative blood type have been observed to come from the western region of Mongolia.
In Japan, AB is the rarest blood type, while Type A is the most common one, followed by type O.
Fun Facts About A+ Blood
– Presence of mind, serious, patient, calm & cool. – Coherent character, can be relied on & trusted, but stubborn. – Plan everything out beforehand, and carry out tasks with seriousness and consistency. – Try to be fair and find the ideal outcome to any situation.
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.
A positive: 30% A negative: 8% B positive: 8% B negative: 2%
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.
1 in 3 people are A positive, which is why it is one of the most common blood types. As you can imagine A positive blood is in high demand, because it is presence in a large percentage of the population.
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.
