Detailed explanation-1: -Usually, an AB parent and an A parent can only have children who are Type A or Type B. One exception is in certain Asian groups. Some of these folks have a rare version of the ABO blood type gene called cis-AB. People with this gene version have an AB blood type but can easily have an O child.
Detailed explanation-2: -If one parent has A and another has O, they can either produce a child with A or O blood types.
Detailed explanation-3: -A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).
Detailed explanation-4: -Blood type is based on genes from each parent. So if one parent is type O and one is type A, the baby will likely be type A. 6 The reason the baby wouldn’t have type O blood is because the gene for O is recessive (meaning it’s only expressed if the baby gets it from both parents).
