The A1 blood group is a subtype of the ABO blood group system, specifically referring to individuals with type A blood who have a specific genetic variation. In the ABO system, the presence of A antigens on red blood cells categorizes blood as type A, while the A1 subgroup is characterized by a stronger expression of these antigens compared to the A2 subgroup. This distinction can have implications in blood transfusions and organ transplants, as compatibility is critical for successful outcomes.
no
yes
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.
S. Very rare
Yes it is. A person with AA positive or AO positive both have blood type A positive. The designation is because you have one "letter" from each parent - and your "letters" determine what your children can inherit.
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.
A1B ve and AB ve blood groups are not the same, but they are closely related. A1B refers to a specific subtype of the AB blood group, where "A1" indicates a particular antigen variant on the red blood cells. Both groups share the AB blood type characteristics, but the presence of the A1 antigen distinguishes A1B from the broader AB category.
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.
