We studied ABO blood groups in Type2 Diabetes Mellitus who are having parental background. In our study the results showing that B and O Blood groups are more associated with the parental History of Diabetes. B and O groups are more associated with the Females with the parental History and A and O groups are more associated with the Males having parental History.
