Answer
Individual 1 can have the genotype either IAi (A blood type) or IBi (B blood type), or be homozygous, resulting in types AA, AB, BB, or OO. Assuming an A phenotype, the genotype for Individual 1 is likely IAi.

Answer
For Individual 2, given that the ABO blood group possibilities include A, B, AB, and O, the genotype can be AIi, Aii, BIi, Bii, AB, or ii. Assuming a B phenotype is presented in the question, the possible genotype for Individual 2 can likely be IBi.
