During lab testing, the tech can only tell you "Type O", but the baby receives a gene from each parent, and neither parent may be "Type O". How can this be?
The essential elements of Type O blood:
- Phenotype (what you can test for) = Type O
- Genotype (what the DNA codes for) = Type OO
- One parent MUST contribute the O gene
- Other parent MUST contribute second O gene
- Blood cell becomes "O" due to NO antigens (identifier) on the cell membrane
- Plasma (blood fluid) will carry the anti-B & anti-A antibodies in Type O blood

How would you represent the genotype for a woman who is hybrid for a type of A blood?
A woman with type A blood may have genotype AO or AA. The heterozygous type is AO.
Which genotype would result in blood type a?
AA,Ai
What blood type a baby will be if father is o and mother is a?
The genotype of the father is certainly OO (because blood type O is recessive). The genotype of the mother however can be AO or AA (both give blood type A). The baby will have a combination of the genes from the mother and the father (one of each) and so: - If the genotype of the mother is AA and the genotype of the father is OO, the baby will certainly have AO as genotype and has therefore blood type A. -If the genotype of the mother is AO and the genotype of the father is OO, the baby can have AO or OO as genotype. AO results in blood type A and OO in blood type O (50% chance).

Two siblings are O- born first and then A . The father was O What blood type must the mother be?
The mother would have to be type A. Father has genotype (0,0) Mother would need to have genotype (A,0) - fenotype (blood group) = A
What will be the blood group of a child if the parents were bb?
If both parents are genotype BB, the child can only be blood type B. The child's genotype would also be BB.
Can a blood type O father give blood type A to his offspring?
It depends on the mother's genotype. O blood is recessive, so the father has OO blood. Both A and B are dominant, so an AA or AO genotype would result in a type A blood phenotype. Since the father is homozygous recessive, he must donate an O. Therefore, for the child to be type A, the mother must donate an A to create an AO genotype for the child. So, if the mother has type A blood or type AB blood, the child could have type A blood.
What possible blood genotype would give group o?
There is only one possible blood genotype that gives group O. The person must be homozygous for type O.
What are the chances of a woman with blood type b and a man with blood type ab having a child with type 0?
There is no chance that this baby would have the blood type O. In order for someone to have the blood type O, the genotype must be IoIo. That means that each parent would have to have an O allele in their genotype. In this case only the mother has the possibility of having an O allele. Genotypes of blood type A: IbIb, IbIo Genotype of blood type AB: IaIb Genotype of blood type O: IoIo here is a punit square to show you heterozygous mommy heterozygous daddy IbIo IaIb Ib Io Ib IbIb IbIo Ia IaIb IbIo This child would have 75% chance of having the blood type B and 25% chance of being type AB
What is the blood type of a woman with the genotype IA at the ABO locus?
Her blood type will be A.
What blood type can be found in an offspring if a mother has type AB blood and the father has type A blood?
The mother is genotype AB, the father is either genotype BO or BB. If the father is genotype BO, the children can be genotype AB, AO, BB, or BO. This results in children with phenotype blood types of: AB, A, or B. If the father is genotype BB, the children can be genotype AB, AB, BB, or BB. This results in children with phenotype blood types of: AB or B.
What blood type can be found in an offspring if a mother has a type AB blood and the father has type A blood?
The mother is genotype AB, the father is either genotype BO or BB. If the father is genotype BO, the children can be genotype AB, AO, BB, or BO. This results in children with phenotype blood types of: AB, A, or B. If the father is genotype BB, the children can be genotype AB, AB, BB, or BB. This results in children with phenotype blood types of: AB or B.
