Can a baby get their blood type only from one of their parents?

If your Parents were blood type A and blood type B, you could be blood type AB, A, B or o. This can occur because o is an autosomnal recessive gene, hence it is written with a lower case letter, whereas A and B are autosomnal dominant. If your parents are blood type A and B, they could (from their mother/father) have genotype AA or Ao, and BB or Bo respectively. You inherit just one of these genotypes, randomly, from each of your parents, thus if your parents are Ao and Bo respectively, you coudl get the A off one, and the o of the other, and thus have blood type A, or vice versa with the B and be blood type B, or if you got the A and the B you would be blood type AB, or with the o and the o be blood type o. Similarly, if your parents were blood type o (o is caused by oo genotype only) and either A or B, depending if the parent with the A or B blood group was AA/BB or Ao/Bo you could only be one of the blood types that your parents are. I hope this clears things up.
