I'm working on an emergency id card for my Baby Sister and we don't know her blood type.
This is an elemenatary biology/genetics question but I just don't know the answer...

Yes, if yours is O and your father's is O, your mother's was also O. There is a small chance that you mother was O- (O negative). Does your dad recall if you had a blood transfusion when you were born? If so, she was O-.

No its not necessary that ur mom's blood gp was O+
she might have O+,O-,A+,A-,B+,B-
following information can help u further:
The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies. The antigens are located on the surface of the red blood cells and the antibodies are in the blood plasma. Individuals have different types and combinations of these molecules. The blood group you belong to depends on what you have inherited from your parents.
There are more than 20 genetically determined blood group systems known today, but the AB0 and Rh systems are the most important ones used for blood transfusions. Not all blood groups are compatible with each other. Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals.
Nobel Laureate Karl Landsteiner was involved in the discovery of both the AB0 and Rh blood groups.
AB0 blood grouping system
According to the AB0 blood typing system there are four different kinds of blood types: A, B, AB or 0 (null).
Do you know which blood group you belong to?
Blood typing – how do you find out to which blood group someone belongs?
A person with A+ blood receives B+ blood. The B antibodies (yellow) in the A+ blood attack the foreign red blood cells by binding to them. The B antibodies in the A+ blood bind the antigens in the B+ blood and agglutination occurs. This is dangerous because the agglutinated red blood cells break after a while and their contents leak out and become toxic.
1.
You mix the blood with three different reagents including either of the three different antibodies, A, B or Rh antibodies.
2.
Then you take a look at what has happened. In which mixtures has agglutination occurred? The agglutination indicates that the blood has reacted with a certain antibody and therefore is not compatible with blood containing that kind of antibody. If the blood does not agglutinate, it indicates that the blood does not have the antigens binding the special antibody in the reagent.
3.
If you know which antigens are in the person's blood, it's easy to figure out which blood group he or she belongs to!
What is happening when the blood clumps or agglutinates?
For a blood transfusion to be successful, AB0 and Rh blood groups must be compatible between the donor blood and the patient blood. If they are not, the red blood cells from the donated blood will clump or agglutinate. The agglutinated red cells can clog blood vessels and stop the circulation of the blood to various parts of the body. The agglutinated red blood cells also crack and its contents leak out in the body. The red blood cells contain hemoglobin which becomes toxic when outside the cell. This can have fatal consequences for the patient.
The A antigen and the A antibodies can bind to each other in the same way that the B antigens can bind to the B antibodies. This is what would happen if, for instance, a B blood person receives blood from an A blood person. The red blood cells will be linked together, like bunches of grapes, by the antibodies. As mentioned earlier, this clumping could lead to death.
offcourse you can always give A blood to persons with blood group A, B blood to a person with blood group B and so on. But in some cases you can receive blood with another type of blood group, or donate blood to a person with another kind of blood group.

Your mom could have been O+, A+, A-, B+, B-. Do you know what your grandma and grandpas blood types were-are? That info could help you find out your moms.

O could have been your moms blood type or it may not have been, unfortunatly O blood can come to children even if neither parent had it, so there is no way to tell that definatly

As you may know, there are several Rh factors (at least D through G) and any one of them may be present or not. If any one of them is present, you are considered as positive. Do you know which antigens you and your father have? Your mother could have been O- or O+ for a different antigen than your dad.

No. You could have inherited your dad's blood type. Your mom's could have been something else. A child will inherit either their mom's or their dad's blood type or a mixture of both of them.

No your mother could have been A or B. My dad was O+ and my mom was A+. Your mother could not have been AB.
