I^{0}I^{0}\times I^{A}I^{B}
gamets        gamets-I^{A}
I^{0}                            I^{B}
I^{0}                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
Genes I^{A} and I^{B} are dominant are I^{0} and
Genes I^{A} and I^{B} are co-dominant
genotypes of the offspring - I^{A}I^{0}, I^{B}I^{0},I^{A}I^{0},I^{B}I^{0}
Phenotypes of the offspring-  A      ,   B     ,   A       ,   B
Hence, the progeny would have either blood group A or B
