Answer:
If a person with blood type A, of unknown genotype, and a person with blood type O have offspring, the only possible blood types in children are A and O.
Explanation:
It should be noted that in the case of blood type A, the possible genotypes are A|A or A|O, while blood type O (recessive) will always have genotype O|O. Assuming that it is the father who has the blood group A:
♂ A|A or A|O
♀ O|O
- Cross 1: If the father possesses the dominant A characteristic on both alleles
Alleles A A
O A|O A|O
O A|O A|O
In this case all the offspring will have a blood type A, with a heterozygous genotype.
- Cross 2: If the father has blood type A, but with a heterozygous genotype
Alleles A O
O A|O O|O
O A|O O|O
50% of the descendants will be of blood type A, heterozygous
The other 50% will be blood type O.
Blood type is determined by the presence or absence of surface antigens A and B.
Thus, depending on the genotype of one of the parents A|A or A|O, when crossed with a parent type O O|O, their children may have blood type A or O.

A person with type A blood (unknown genotype) marries a person with type O blood, the possibilities are A, B and O blood group.
Blood group is the classification of blood on the basis of the presence and absence of antibodies and antigens.
Given that, A person with type A blood (unknown genotype) marries a person with type O blood.
We don't know the genotype
If the unknown person is OO you get O.
The person is AA or AO you get A or O.
If the person is BB or BO you get B or O.
If the person is AB you will get A or B, there is no chance of an O offspring with an AB parent.
Thus, the possible blood group is A, B, and O.
