no. The possible blood types of an offspring are A, B, and AB. in order to have a recesive gene have a possibility of appeaing in the child oth the mother and father must carry the gene.

What is the genotype of a woman with A blood and a man with b blood and a child with o blood?
In this case both parents must be heterozygous to have this child. This means the mother will have the genotype AO and the father will have the genotype BO. In order to have blood type O, the child must have the genotype OO.
If one parent has a blood type of B-positive and the other has A-positive can their child have B-negative?
No. A person's blood type is made of up contributions from both your mother and your father. O blood types (whether positive or negative) are really OO. So no matter whether you get the first O or the second O, all resulting children must be OO. For example, my mother is an OO, and my supposed father was an AO. I am a type B, so there is no way that I am that man's child (my mother just recently confirmed that there could have been someone else). Blood types resulting from my mother and "father" could be A (AO), or O (OO), but that is it. O is a recessionary gene, that is why a person with type O blood can only contribute O's to their children. In order to be type O, you must be an OO.
Can a man with blood group o positive be father to a baby with blood group o?
Yes, so long as the mother isn't O. The negative gene is recessive.
A man of blood group B is being sued by a woman of blood group A for paternity. The womans child is blood group O Can this man be the father of this child?
could if he is IBi
Can a man with ab negative blood and a mother with o positive blood have a son with a positive blood?
there is a 50% chance of this
What is the genotype of a woman with A blood and a man with b blood and a child with o blood?
In this case both parents must be heterozygous to have this child. This means the mother will have the genotype AO and the father will have the genotype BO. In order to have blood type O, the child must have the genotype OO.
A man heterozygous for blood type A marries a woman heterozygous for blood type B The chance that their first child will have type O blood?
25% for blood type O, 50% for blodd type AB, and 25% for A.
Can you father someone who has type O blood?
A man with any blood type by AB can father a child with type O blood. A parent heterozygous for type A or B may have a child with type O.
If a child has blood type O and its mother has type O could a man with type B be the father?
Yes it is possible. Blood type O is recessive. So it is true that the child would need an OO blood type. But if the mother is OO and the father is BO..... Then in this case the mother would contribute an "O" and the father a B or an O. If the father contributes an O then the child will be type O. Of course in order for this to happen the father must be heterozygous and not homozygous for the dominant blood type.
Could a man with O blood father a A child?
Yes, as long as the mother has a strong A blood type
Can a man with O rh plus and a woman with O rh plus have a child with O rh- blood?
Yes - it is possible. Firstly, if both parents have the blood type O, then the child must also have blood type O. Rh positive is dominant, so a person who is Rh + may be heterozygous (Rh+/Rh-). Both parents in this case would need to be heterozygous for the child to be Rh-.
Can a man with blood type b and a woman with blood type ab have a child with blood type b?
No. The father must be of type A if the child is and the mother is not.
If a child has blood type O and its mother has type A could a man with type AB be the father?
no
How is it possible for a man with blood type b and a woman with blood type a to have a child with blood type o?
This is possible if the man is heterozygous for blood type A (Ai, not AA). Each parent passes down one allele to a child. So, if the woman is type O (ii) and the man is heterozygous for A (Ai), the child receives i from the mom and A or i from the dad. Consequently, the children can be either type O (ii) or A (Ai).
If one parent has a blood type of B-positive and the other has A-positive can their child have B-negative?
No. A person's blood type is made of up contributions from both your mother and your father. O blood types (whether positive or negative) are really OO.

O is a recessionary gene, that is why a person with type O blood can only contribute O's to their children. In order to be type O, you must be an OO.
Can a man with blood type a negative have a child with a lady with blood type a positive?
Yes. My mother is O positive and my father is O negative and I am O negative
Can a man with type B negative blood father a child with A positive blood if the mother has O negative?
No because it's not possible for those to blood types to creat O negative
