how is blood group of a offspring defined if blood gr of father is A,whereas mother's is O. which one is dominant and why?can this appear in exams?

Dear student,
We cannot determine the blood group of the offspring in this case. This is because the genotype of the blood groups is not given, only the phenotype is given. The blood group A could be homozygous or heterozygous. So if the father is heterozygous, the offspring could have either blood group A or blood group O. So just with this information, we cannot determine the dominnat blood group.

(a) Which trait (rolling or not rolling) is controlled by the recessive allele? (b) State all possible genotypes of the F1 generation of the cross. Show the inheritance of the tongue rolling in humans in the given example using a suitable cross. What percentage of offspring will show the same genotype as the parents? OR (c) If one of the parents could not roll their tongue, with the help of a cross, calculate the ratio of tongue- rollers to non-tongue-rollers in the off springs.​
