A positive and A1 positive (usually written as A plus sign and A1 plus sign) refers to the antigens in the blood. People with the A blood type contain A antigens. People with A positive blood refers to the presence of both A antigens and Rh-positive antigens.
A1 is a subgroup of A group which contains a lower amount of A antigen than A group and represents 80% of group A donors.
Yes! There are two subtypes of the A-bloodgroup: 80% have group A1, and 20% have group A2. This is relevant in the donations of organs. Group A2 activates the immune defence in the recipient a lot less, which is good. People with group A2 are therefore preffered as donors. But I think that if you'll ever need a kidney yourself, you're better off with having group A1.
Because not every one has the same blood type and you need to know what blood type your giving to the recipiant of the blood because if you give some one the wrong blood type you can kill them.
When the parents are with blood group AB and O, the possible blood group of the child would be either A or B. This is because the blood group AB has the genotype AB and blood group O has the genotype OO. Thus upon recombination, the only outcomes would be AO - meaning blood group A, or BO- meaning blood group B.

There is no cell A1A2. What you may mean is A1:A2 which refers to the range consisting of cell A1 and cell A2.
