What are the possible blood types of an offspring from a type A mother and a type AB father?
|
|
A, B, AB and O
|

|
|
A and B
|
|
|
A only
|
Explanation:
Detailed explanation-1: -One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types.
Detailed explanation-2: -In most cases, an O parent and an AB parent will have only A or B kids.
Detailed explanation-3: -IA/IB people have both phenotypes, because A and B express a special dominance relationship: codominance, which means that type A and B parents can have an AB child. If both the parents are AB then their genotypes will be IA/IB and this combination cannot give rise to O blood group.
