OA Adeyemo, OB Soboyejo


One hundred and fifty students (150) were randomly selected from the Department of Cell Biology and Genetics of University of Lagos, Akoka, Nigeria for ABO, RH blood groups and 6 haemoglobin genotypes studies. Blood group O was the highest with the percentage frequency of 55.3%, followed by blood group A (25.3%), B (16.7%) and the least percentage frequency was blood group AB which is 2.7%. The RhD distribution also varies among the four (4) ABO blood groups. The total percentage of
RhD positive was 94% and that of RhD negative was found to be 6%. When the students were screened for haemoglobin genotypes the percentage frequency for the haemoglobin genotypes for HbAA, HbAS, HbSS, HbAC, HbSC were 70%, 26%, 1.3%, and 0.7%, respectively.
