This study showed that
blood group O was the highest with a frequency distribution of 50% followed by
blood group B with a frequency distribution of 26%, blood group A 21% and the
least frequency distribution is that of blood group AB with 3%. Gene
frequencies with respect to the ABO system for the present study has shown a
general formula: O>B>A>AB indicating a superiority of allele B over allele
A. This is in correlation with the study made by Chima, et al., (2012) which shows a total of 5,000 consecutive blood
donors’ samples grouped for ABO and Rhesus D antigen where blood group O, B, A
and AB was 57.2%, 20.7%, 20.5% and 1.6% respectively. When compared with other
reports from similar studies carried out in different countries of the world,
the data is consistent with previous findings from other parts. 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%, 4.7% in the
order of O>B>A>AB (Loua, et al.,
2007).

However, this is not in
consonance with some other studies that reported the frequencies of ABO system
in the order of O>A>B>AB (Odukuma, 2007). This result is similar to
the result obtained by Bakare, Azeez and Agbolade (2006) among 7,653
individuals in Ogbomosho, Oyo State in Nigeria where blood group A, B, AB and O
had 22.9%, 21.3%, 5.9% and 50% respectively. Also in Benin, Niger Delta region
of Nigeria, blood A, B, AB and O as 23.73%, 20.9%, 2.97% and 53.2% respectively
(Enosolease and Bazuaye, 2008).

This study further
confirmed that Rhesus positive has the highest percentage while Rhesus negative
was lower compared to the positive. In this study, it was observed that blood
group O positive is the highest with a percentage of 49% which is followed by
group B positive with a percentage frequency of 25%, group A positive is 19%
and AB positive is 3%. The total percentage of Rhesus positive was 96% and that
of Rhesus negative was found to be 4%. Rhesus positive was 96% and that of
Rhesus negative was found to be 4%. Rhesus positive is higher in females for
blood group O and B than in male but none was in AB and the percentage
frequency was the same for blood group A.

This is similar to the
research carried out by Odukuma et al.,
(2007) in Abraka, Delta State of seven hundred and ninety-five (795) volunteers
tested. 98.2% were Rh D positive and 1.8% were Rh D negative during the cause
of study. This is similar to previous studies done at Ibadan and Enugu in
Nigeria. It is also similar to previously reported among African subjects, West
Indians and blacks in Great Britain. This results are however different from
those reported from Eastern highlands of Papua New Guinea where the entire
population were reported to be 100% Rh D positive (Salmon, 1988 as cited in Odukuma,
2007).
