How do you change genotypes, like AO and BO to phenotypes?

In the given examples, the phenotypes will be A and B.

Explanation:

Genotypes denote the presence of genes in pairs while phenotypes denote the physical expression of those genes.

In the examples given, while the genotype is either AO or BO (which means that one gene codes for A or B surface antigen, the other codes for no surface antigen), the presence of either A or B in the gene pair will cause expression of the A or B surface antigen.

Hence, the phenotype will be A or B.

In short, the phenotype will depend on the expression of the characteristic coded for by one or both of the genes present.
