YES...DR.V is in the house...and got your answers for ya!!
Ain't nothing really just that you can't give each other bloods if needed.
They lack A or B antigens...meaning:
Type 0- is basically the universal donor and can donate blood to any type, where the 0+ cannot..so if you are 0-, you can give blood to your wife but she can't do the same for you ..but 0+ can be given to any persons with type A,B,..So anyone with type 0+ is really going to have a hard time finding a donor, and that really sucks..
With due respect, I think you got your facts a lil twisted. O+ ppl can only give blood to another O+. He CANNOT give blood to ppl with type A or B blood group due to the Rhesus factor. Only O- can donate their blood to all other blood groups. That is why it is called the Universal Donor. Those with AB blood group on the other hand are known as universal Recepients becoz they can receive blood from all other blood groups. Coming to think of it, it is the O- people who need to be more cautious as not many ppl have O- blood. O+ ppl are rather lucky. Nowdays many are O+. I am O+ myself n i have lotsa ppl i know who are O+. Lucky for me.
