Detailed explanation-1: -Similarly, someone who is blood type B could have a genotype of either BB or BO.
Detailed explanation-2: -Genotypes BB and BO have Type B Blood Genotypes BB and BO refer to individuals having either two “B” alleles for blood type, or one “B” allele and one “O” allele. Both of those genotypes results in having Type B blood. The BO genotype results in Type B blood because B is dominant over O.
Detailed explanation-3: -Individuals with either the IAIA or IAi genotypes have blood type A. Those with IBIB or IBi have blood type B. Those with IAIB have blood type AB, and those with ii have blood type O.
Detailed explanation-4: -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-5: -IA, IB both are dominant forms so, person with ii allele have O blood group. Thus people with IAIA or IA i have blood group A and individuals having IBIB or IB i genotype have B blood group. Whereas person having genotype IAIB show phenotype AB and individuals with genotype ii have phenotype O [2].
