I have AB + blood type. My ancestors were mainly Finnish, Sami, and a tiny bit of French many generations back
AB blood type can be created by combining A and B blood types.
there are 8 types of blood a+, b+, o+, ab+,a-,b-,o-,ab-
Blood type A can receive a transfusion from blood types A and AB.
When donating blood they can only be given to a specific blood type. Type A can be given to A or AB blood types only. Type B can be given to B or AB blood types only. Type AB can only be given to AB. While type O can be given to all type A, B, AB and O blood types.
Blood AB.
A person with phenotype AB blood must have genotype AB blood. Meaning that the person has inherited both A and B alleles.
The AB blood type is known as the universal recipient. Therefore, the groups that a person with this blood type can give blood to are limited. If your blood is AB+, then you can only give to others with AB+ blood. If your blood is AB-, then you can give to people with both AB+ or AB- blood.
It's important for anyone who can donate blood to donate, but the fact is that AB is not a donor for any blood type but its own. AB can only donate to AB. AB is, however, what is referred to as a universal recipient, meaning that someone with type AB blood can receive blood from AB, A, B, and O blood types. This being the case, it wouldn't seem that a shortage of AB blood would be a problem unless there is a generalized blood shortage of all types (which there usually is, so donate if you can spare a pint!)
An AB negative (AB-) individual can donate blood to recipients with AB+, AB-, A+, and A- blood types. This is because AB- blood contains both A and B antigens, making it compatible with those who have AB blood types, and it lacks the Rh factor, allowing it to be safely transfused to Rh-negative individuals. However, they cannot donate to O or B blood types, as those recipients would produce antibodies against the A and B antigens present in AB blood.

Well for starters we would have to see what RH group you are in you see AB+ can receive blood from people that are A+ A- B+ B- O+ O- AB+ AB- but can only give to people that are AB+.If you are AB- you can receive from blood types A- B- O- and AB- but you can give to people that are AB+ and AB-.
People who have AB blood are the universal recipient. They can receive blood from any blood type which can come in handy in an emergency situation requiring blood.
