Parents
blood types: A and B
genotypes: IAi and IBi
Children
blood types: A, B, O, and AB
genotypes: IAi, IBi, Ii, and IAIB
(capital A's and B's are superscript)
The possible genotypes for blood type A are AA and AO.
The two possible genotypes for blood type A are AA and AO.
The two possible genotypes for a person with blood type A are AA and AO.
AO or AA
Individuals with blood type O can have the genotypes OO or Oi, where "i" represents the recessive allele for blood type O.
Possible genotypes for a person with type B blood are IBIB or IBi, where IB represents the gene for type B blood and i represents the gene for type O blood.

BB or Bo normally.
If the first person is AA, then the possible resulting genotypes are AA or AB. If the first person is AO, then the possible resulting genotypes are AA, AB or BO.
The Basic Blood Group genotypes would be: AA AO AB BB BO OO Blood type A--AA AO Blood type B--BB BO Blood type AB--AB Blood type O--OO
If the parents both have the genotype Aa, their children could have the genotypes AA, Aa, or aa. The possible phenotypes for their children would be individuals with type A blood (AA or Aa genotype) or type O blood (aa genotype).
Although there are actually several genes which determine ABO-type, they are usually placed into the three basic groups i.e. A, B and O.For each phenotype, the genotypes follow:O: OO is the only possibility.A: AA or AO are both acceptable.B: BB or BO are both acceptable.AB: AB is the only possibility.
