In the ABO blood group system, genetically the symbol or allelic pattern for individuals in the A group can either be IAi or IAIA, and the B group can either be IBi or IBIB.  The genetic symbol that represents the O group is ii.  The capital I represents enzymes that catalyze reactions to express a specific blood group. If you watched the Khan Academy video (Genetics study video resources), then the context of the question sounds familiar except in the video the presenter listed ii as O so the genoypes were depicted as AO, OO etc.). Based on the genetic information provided, you can extrapolate the following:
