Detailed explanation-1: -In order for a person to have type A blood, their genotype must be either AA or AO. A person must have inherited an A allele from at least one parent. They cannot have inherited a B allele from either parent.
Detailed explanation-2: -If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO.
Detailed explanation-3: -The ABO blood group antigens are encoded by one genetic locus, the ABO locus, which has three alternative (allelic) forms-A, B, and O. A child receives one of the three alleles from each parent, giving rise to six possible genotypes and four possible blood types (phenotypes).
Detailed explanation-4: -If you have an AA or AO genotype, you will have the phenotype of type A blood; if you have a BB or BO genotype, you will have a type B blood phenotype; if you have an AB genotype, you will have a type AB blood phenotype; and if you have an OO genotype, you will have a type O blood phenotype.
Detailed explanation-5: -If your blood is A positive (A+), it means that your blood contains type-A antigens with the presence of a protein called the rhesus (Rh) factor. Antigens are markers on the surface of a blood cell. According to the American Red Cross, this is one of the most common blood types.
