What blood type if parents are AB and O?
In most cases, an O parent and an AB parent will have only A or B kids. It is only very rarely that they might have an AB or an O child (see the links at the end for these exceptions). Isn’t genetics fun! What I’ll do for the rest of this answer is go through why an O parent and an AB parent will have only A or B kids.
Can AB and O make AB?
An AB and O couple producing an AB child cannot be explained in terms of the usual inheritance patterns. One would not expect the cord blood result to be AB when the mother is type O, however, in very rare instances, such as the cis-AB blood type, it is possible.
Can a child with O blood group have parents with blood group A and B?
A child with O blood group cannot have parents with the genotype.
Can two parents with type O blood have a child with AB blood?
Keep in mind, though, that mutations are very rare. Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely).
Can AB and O have an O child?
Can an AB father and an A mother have an O baby? Yes they can. An AB parent can indeed sometimes have an O child. But it is by no means common.
How can two parents with blood type A have a child with O?
Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there’s 1 in 4 or 25\% chance for a child to have OO, or blood type O. How did I get a 1 in 4 chance?
What blood types can be produced by two different parents?
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. If one parent has A and another has O, they can either produce a child with A or O blood types. Rh Positive (Rh+) and Negative (Rh-) Blood Types
Can blood type AB people have blood type O offspring?
The claim that blood type AB people cannot have blood type O offspring and vice versa is false. There is a phenomenon called cisAB where both, the A and the B are encoded into one allele.
Can two people with B blood type have a baby?
Two parents with B blood type can produce a child with either B or O blood type. 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.
How do you calculate the blood type of your offspring?
You can use our blood type Punnett square calculator to calculate the genotype of your offspring. Write down your blood type and your type’s allele like AA or AO. According to your allele, your child will probably have A-type (75\% chance) or O type (25\% chance). Write down your partner’s blood type and alleles which will be AB.
