A man with blood group A marries with a woman with blood group O and their daughter has blood group O. Is this information enough to tell you which of the traits- blood group A or O- is dominant? Why or why not? can u explain this question with a monohybrid cross as even if the father has ao and mother has oa....in o blood group it can either be oa or oo in both cases o is dominant. Thank You

Expert Answer:
No. This information is insufficient. This is because the genotype of the parents is not given, without which we cannot predict whether the trait is dominant or recessive.
(Actually, the blood group O is recessive and A and B are the dominant blood groups, but that is something that has been understood through studies. With the information given above, we cannot deduce this)
