Explanation:
Detailed explanation-1: -Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO.
Detailed explanation-2: -Remember, because type O blood results from the homozygous recessive genotype (i i ), the only way to produce a type O child is if both parents provide an O allele (i ).
Detailed explanation-3: -In general, does a child usually have the same blood type as one of their parent’s blood type? While a child could have the same blood type as one of his/her parents, it doesn’t always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B.
