We are looking for the possible blood types of the PARENTS

Available information:

  • Baby type AB Rh neg >> can only be AB (--)
  • one parent contributed A(-) gene & other B(-) gene
Baby receives one gene from each parent:

note: Each parent can be Rh pos (+-) or Rh neg (--) >> assume the selection of (-)

  • Mama AB + Papa AB = baby AB, AA, BB
  • Mama AA + Papa AB = baby AB, AA
  • Mama AA + Papa BB = baby AB
  • Mama AA + Papa BO = baby AB, AO,
  • Mama AO + Papa AB = baby AB, AA, BO
  • Mama AO + Papa BB = baby AB, BO
  • Mama AO + Papa BO = baby AB, OO
There are 7 possible combinations of parents to produce a Type AB baby.

Type AB baby is guaranteed with the Type AA and Type BB combination.

Most likely your blood type would me AB. Your advantage i that you can receive any type of blood, such as A, B, or O blood. O is unlucky because it can only receive O blood, but it can donate blood to any blood type.

Anything other than O. This includes both rhesus-positive and -negative for all of AB, A and B.

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 a woman with blood type A has a baby with blood type AB a man with blood type O be the father?

There is no possible way that this man is the father of this baby because he would have passed down a bloodtype gene to give this child at least part O blood.


If a mother has blood type O-negative and the father has blood type A-positive what are the possible blood type outcomes of their children including the positive and negative aspects?

I'm an O- mother of three (3) with an A+ father.The bloodtype/s of your offspring can vary.....Our firstborn, (son) was born with my blood type= O-our second born, (daughter) has her father's blood type= A+and our youngest, (son) has a mixture of the two= A-While I couldn't tell you whether an O+ outcome is possible, {my guess is it would be?!} I will say I was happy with the outcome in our family...it's kinda cute really.......that my eldest boy shares my B/T; our daughter shares her father's & our 'baby' had to be different & was born with a concuction of both.I hope this satisfies any curiosity & answers your's, & other's Q.


Does father has same type of blood with their children?

Yes this is possible, but not a must.


Can a child have O blood group if both parents have A and 3 grandparents A and 1 grand parent AB blood groups?

Yes, this is possible given the scenario. The child would have inherited both recessive alleles (OO) from its parents, meaning both parents were heterozygous for bloodtype A - AO. Each parent could have obtained this bloodtype with 3 grandparents type A and one type AB. Parent 1, for example, with two A type parents: both parents could have been AO or one could have been AA and the other AO. Parent 2, with an A type parent and an AB parent: the A type parent would be AO and the other, obviously, AB.

What is the best type of blood to receive if you need blood?

O negative can be given to a person with any bloodtype, but if possible it is better for a person requiring transfusion to be given blood matching their own bloodtype.

Is it possible to change your rhesus factor?

"Rhesus factor" refers only to the presence or absence of the RhD antigen, symbolised by negative (absence) or positive (presence). Because it is caused by genetics, it cannot be changed by any artificial means, although it may change naturally - there are several documented cases of people changing bloodtype.
