An individual inherited the following genotype Sese Hh AO. Which soluble antigens would be detectable in the saliva?

Explanation:
ABH antigens in saliva depend on secretor status and the ABO genotype. Being a secretor (Sese) means ABH substances can be secreted into saliva. The H gene is Hh, so H antigen is produced in secretions. With an ABO genotype of AO, there is A transferase available to convert H antigen into A antigen in secretions. Therefore, both H antigen and A antigen would be detectable in saliva. There is no B antigen because there is no B allele.
