MICROANATOMY

Detailed explanation-1: -Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO.

Detailed explanation-2: -IAIB is the genotype of human blood group AB. Human blood type is determined by co-dominant alleles.

Detailed explanation-3: -Blood group in human beings have four phenotypes namely A, B, AB and O. Blood group A has two genotypes (IAIA, IAi), blood group B has two genotypes (IBIB, IBi) and blood group AB (IAIB) and O (i i) have one genotype each.

Detailed explanation-4: -When one of the inherited alleles is A and the other is B, the genotype is heterozygous and the blood type is AB. AB blood type is an example of co-dominance since both traits are expressed equally. Type A: The genotype is either AA or AO.

Detailed explanation-5: -Genotypes AA and AO refer to individuals having either two “A” alleles for blood type, or one “A” allele and one “O” allele. Both of those genotypes results in having Type A blood. The AO genotype results in Type A blood because A is dominant over O.
