It was found that Basques have the highest concentration of type O blood in the world ? more than 50% of the population, with an even higher percentage in remote areas where Basque is more widely spoken. Basques also have a higher incidence of Rhesus-negative blood than anyone else in the world.
Rh-negative frequencies of about 29% were documented among Basques and in distinct populations living in the High Atlas Range of Morocco [25], which have the highest reported prevalence of Rh-negative phenotypes apart from that from Saudi Arabia above.
Your blood is Rh negative. Fifteen percent (15%) of the population has Rh negative blood and the rest are Rh positive. Being Rh negative is not a disease. It is just an inherited trait, the same as eye color.
About 17 per cent of Australians have Rh negative blood and it usually causes no health problems.
The most common blood type in Australia is O positive and the least common is AB negative.
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).
Rh- is rare partially because of how it is inherited: Rh- is a recessive trait. A recessive trait is only visible when you inherit it from both parents. In contrast, a dominant trait shows up even if you only inherit it from one parent. So someone with DNA for both Rh+ and Rh- will have positive type blood.
There are four main blood types. Blood type A is the oldest, and existed even before the human race evolved from our ancestors.
Having an Rh negative blood type is not an illness, and it usually does not affect your health. But it can affect pregnancy. Your pregnancy needs special care if you're Rh negative and your baby is Rh positive. That's called Rh incompatibility.
Of all the negative blood types (AB-, O-, A-, and B-), those of Asian descent have the lowest percentage. These figures highlight the fact that it is not a common blood type in Asia. This in turn means that hospitals and medical facilities will not usually keep a large stock of Rh negative blood.
Your blood type depends on the genes you inherit from your parents. Whether you're RhD positive or negative depends on how many copies of the RhD antigen you've inherited. You can inherit one copy of the RhD antigen from your mother or father, a copy from both of them, or none at all.
The Rh factor is an inherited protein that can be found on the surface of the red blood cell. If your blood type is positive, then your blood cells have the Rh protein. If your blood type is negative, then your blood cells lack the Rh protein.
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.
Asian: 39% O-positive, 27% A-positive, and 25% B-positive.
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 ...
Whilst “golden blood” is still part of the Rh system, it is the rarest known type. It is Rh-null: 61 Rh antigens are absent in it. If you're Rh negative, you still have some Rh proteins but you have more missing than you have present. If you're Rh-null, you have none of these antigens at all.
While Shimizu and Colleagues10 found that blood type B was associated with longevity, Mengoli and Colleagues6 and Brecher and Hay12 concluded that group B was inversely correlated with age. In addition, there are isolated reports of group A7 and group O9 being associated with longevity.
Indeed, the authors retrospectively reviewed blood group distribution in a cohort of patients stratified by decade of death and found that patients with group B blood had an overall decreased survival (p<0.01) compared with patients with the other blood groups.
The Rhesus D antigen (RhD) has been associated with susceptibility to several viral infections. Reports suggest that RhD-negative individuals are better protected against infectious diseases and have overall better health.
Taken together, the authors concluded that type O and Rh-negative blood groups may be protective against SARS-CoV-2 infection and illness. In China, Zhao et al [22] conducted a retrospective analysis on 2,173 patients who tested positive for SARS-CoV-2.
However, this study, conducted by Australian Red Cross Lifeblood lead researcher Dr Rena Hirani, uses patient data, which is more reflective of the population, to show that in fact only 14% of the population have a negative blood type, and importantly, just 6.5% are O negative.
Haplogroup M42a is widely accepted as indigenous to Australia, with M42a distantly related to M42b, which is found in the South Indian tribal groups, but with a divergence time of at least 55 KYA.
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.
Rh incompatibility occurs when the mother's blood type is Rh negative and her fetus' blood type is Rh positive. Antibodies from an Rh negative mother may enter the blood stream of her unborn Rh positive infant, damaging the red blood cells (RBCs).
