Abstract:

A study was carried out to determine blood groups of a random population sample from the Mbororo ethnic group in Momo Division in the North West Region of Cameroon. The ABO and RH-D blood groups were collected retrospectively for five years (2009 – 2013) from the records of the Presbyterian General Hospital, Acha Tugi. Out of total of 2000 Mbororos estimated to inhabit Momo Division, the records for 263 individuals were examined for ABO and Rh blood groups. Blood A, B, AB and O were respectively 72 (27.38%), 31 (11.79%), 14 (5.32%) and 146 (55.5%) in the population. This distribution differed significantly (P<0.05) from those expected under the Hardy – Weinberg law. The percentages of the individuals belonging to the different ABO blood groups also varied significantly (P<0.05) during the period of study. On the other hand, 252 (95.82%) individuals were Rh+ve (DD + Dd) while 11 (4.18%) individuals were Rh-ve (dd). This study revealed that the distribution and proportion of individuals belonging to the Rh blood groups did not differ significantly (P>0.05) from those expected under the Hardy–Weinberg law. From these studies it is concluded that phenotypically, O and Rh+ve blood groups were dominant in the Mbororo ethnic group of Momo Division in Cameroon. Also, gene frequencies in this population were in the series: O > A > B > AB.
