How can a person with O blood type be an offspring of a mom with A blood type and a dad with B blood type?

To explain this properly you would have to have a basic understanding of inheritance, but I'll do my best.
Blood groups are inherited as a pair. A and B groups are co-dominant and O is the recessive.
So mum is genotype AA or AO, which would make her group A and dad is genotype BB or BO making him group B.
So baby will inherit one from each parent: so baby could be AB or AO or BO or OO.
If A is inherited from mum and B from dad then baby is group AB if its A from mum and O from dad then its group A; if its O from mum and B from dad then its group B.
If O is inherited from both parents then baby is group O.

Blood type o and blood type ab equals what blood type?
Yes. The Rh factor (the +/- part) is actually two parts with positive being dominate. So, a person with ++ or +- is called positive, and a person with -- is negative. As such; two people with +- blood can have a child with ++, +-, +-, or --. (which simplify down to +, +, +, and -)
If dad has blood type A and mom has blood type B can they have a child with blood type O?
Yes. Type O blood requires that you have two recessive genes, one from each parent. Each of your parents can carry one of these and have a different type of blood. In this case, there is a one in four chances of the child having type O blood.
Can an 0 - Mother and an O plus Father have an baby with an A blood type?
The rhesus factor (positive and negative) isn't important so...The A (and B) blood type genes are dominant over O (which actually just means the lack of A/B). Since mum and dad are both blood type O neither mum or dad have the A gene which means the baby cannot be type A. A different dad (or mum) with blood type A or AB would be needed.
If the Mother is blood type O father is A what should be their child's blood type?
Blood group O is caused by a recessive gene (symbol: i). The mother must therefore be homozygous (ii). The offspring must, like Mum, have two copies of the recessive gene, and one of these must have come from Dad. So the father's possible genotypes are IAi (blood group A), IBi (group B), and ii (group O), all of which include a recessive gene that could be passed on to the offspring.
Your father has A positive blood and your mother has O negative and you recently found out that you are type B what is the likelihood of your dad actually being your dad?
If your father has type A blood and your mother has type O blood, then the only possible blood types for their offspring are type A and type O. If you have type B blood, then one of your parents must have had either type B or type AB blood. It is possible that one of your parents is mistaken about his or her blood type or that the blood test results were inaccurate. It is possible that you are adopted. It is possible that one of your parents is not your biological parent, although this does not mean an affair, since sperm donation is a possibility. Because of a relative having an unusual blood type situation, I discussed it with a geneticist. A bone marrow transplant can occasionally change a person's blood type. Or, whoever did your blood test might have been slow (e.g., interrupted) or inexperienced in processing the sample (e.g., a high school science class), so you might have blood type O but appear to be blood type B. Or, your mother might have the Bombay phenotype that means she has a B, but appears to be an O. (This is what my relative probably had, which was why his blood type test results alternated.) It is also possible that one of your parents is a chimera, but I was told that this was the least likely possibility, so if you want more information on chimeras, check the Wikipedia link below.

If your dad is type A blood and your mum is type B or type AB blood what is your blood type?
A,ab or b
Can a mom a blood type and a dad with b blood type have a child with o blood type?
yes
If your mom has type A blood and your dad has type B blood would you have type AB blood?
Since a person with type A blood could have gene combinations of either O or A, and a person with B blood type could have combinations of O or B; children could express O,A,B.or AB types, with O type being the most likely in half the cases.
Is it possible to have a child with blood type O if the mom has blood type A and the dad has blood type B?
yes
If the mom is o and the dad is a what blood type will be their baby?
The baby will either be blood type O or Type A
Is it possible to have a child with blood type O if the mom has blood type A and dad has blood type B show your work?
Yes.
Should you have the same blood type as your mum?
Not necessarily, you could have the same, you could have the same as your dad, or you could be different. If your mom had type A blood and your dad type B you could possibly have type A, B, AB, or O blood.
Is a blood Type A mom compatible with Type O dad?
There are no compatibility issues with the ABO gene and the production of offspring. There might be an issue if the mother is Rh negative and the father is Rh positive with the resulting baby inheriting the Rh positive gene.
If a Baby has AB blood could its dad have type o blood?
yes
Can a son have a type A blood and his dad have type O?
Yes. If his mother is Type A or Type AB.
Can a blood type a dad have a blood type b son?
Yes. If he's A-null and his wife is B or AB.
