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.
What else can I help you with?
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 a mother has blood type O plus and the father has blood type A plus what are the possible blood type outcomes of their offspring?
Dad can be Ai or Aa (where i represents the recessive gene). In order for a child to be O, he or she has to have neither A nor B allelles. So Mom could be Ai (bloodtype A), Bi(bloodtype B), or Ii (Bloodtype O).
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.
What blood type would a man have to exonerate him from being the father of Type B child whose mother is Type A?
We are looking for the possible blood types of a "NON"-FATHER.Parental information:Mother type A --can be AA or AO - contributes the A or O geneBaby type B --can be BB or BO - has to be BO getting O gene from momBaby receives one gene from each parent: Mom type AO + Dad type BB/BO = Baby type AB, BO, OOMom type AO + Dad type AB = Baby type AA, AO, BB, BOThe father would not be these blood types: Mom type AO + Dad type AA/AO = Baby type AA, AO, OOMom type AO + Dad type OO = Baby AA, OOGenerally, Dad cannot be Type A (no B gene here), nor Type O (OO). HOWEVER: There is more to ABO blood typing that just the ABO gene.There is also an inhibitory gene that will change any genotype into the phenotype O.Therefore a person with genetically AB blood can be tested as having Type O.If the father has the inhibitory gene affecting his B or AB type,then the Type B baby is definitely possible.
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.
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 -)
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.
If a Baby has AB blood could its dad have type o blood?
yes
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.
What antigens are expressed if a person is blood type AB negative?
My daughter is AB negative , I am B positive and her dad it A negative
Can a son have a type A blood and his dad have type O?
Yes. If his mother is Type A or Type AB.
