Human population differs in frequencies of specific
blood groups. This can be seen with the global frequency patterns of the type B
blood allele. It is highest in Central Asia and lowest among the indigenous
people of the Americas and Australia. Overall in the world, B is the rarest ABO
blood allele, only 16% of humanity has it. The A blood allele is somewhat more
common around the world than B, about 21% of all people share the A allele. The
highest frequencies of A allele apparently was absent among Central and South
American Indians. The O blood type was shared by 63% of human around the world,
high frequency among indigenous populations of Central and South America where
it approaches 100%. The lowest frequencies are found in Eastern Europe and
Central Asia (Dennis, 2014).

In Britain, the frequency distribution of O, B, A and
AB are 47%, 42%, 8% and 3% respectively. Also in Guinea, the percentage
frequencies were 48.9%, 23.7%, 22.5% and 4.7% for O, B, A and AB respectively
(Donners, 2012).

According to Chima, et al., (2012) stated that blood groups and Rhesus factors also
differs from different parts of Nigeria. A total of 5000 consecutive blood
donors samples were grouped for ABO and Rhesus D antigen in Aminu Kano Teaching
Hospital, North-Western Nigeria. Blood group O had the highest prevalence of
2,860 (57.2%) followed by blood group B of 1,035 (20.7%), then A of 1,025
(20.5%) and the lowest being AB of 80 (1.6%). A total of 4,741 (94.8%) of the
study group were Rhesus D positive while 259 (5.2%) were Rhesus D negative.

The distribution frequencies of ABO and Rhesus (Rh) blood
groups in Ogbomosho, Oyo State, Nigeria was determined. Overall, a total number
of 7,653 individuals were typed for ABO and Rh groups. 3,824 (50%) were blood
group O. 1,750 (22.9%) were typed group A, 1,629 (21.3%) were blood group B and
450 (5.9) were blood group AB. For the Rh blood group, 6,823 (96.7%) were Rh
positive while 230 (3.3%) were Rh negative. Also, over a twenty year period;
between 1986 and 2005, a total of 160,431 blood samples were grouped for ABO
and Rh D at the University of Benin Teaching Hospital, Benin City, Nigeria.
Blood group distribution among these samples showed phenotype A, B, AB and O as
23.72%, 20.9%, 2.97% and 53.22% respectively. The Rh D negative phenotype was
found among 6.01%) and Rh positive phenotype, 93.99%.

In Abraka Campus of Delta State University, seven
hundred and ninety-five (795) volunteer students were analysed in determining
ABO and Rhesus blood groups, Amongst ABO system, blood group O was most common
followed by A, B and AB respectively. Rhesus positive was more common that Rhesus
negative in the Rhesus system. In the combined ABO and Rhesus blood groups, O
positive was most common, followed by A positive, B positive, AB Positive, O
negative and A negative respectively (Odukuma, 2007).
