What blood group do parents have to have a child with type a blood group?

One parent would need to have:
type AO, AA, or AB
and
rh ++ or +-
and the other parent would need to have:
type BO, BB, or AB
and
rh ++ or +-
A person with AO or AA will have type A blood; a person with ++ or +- will have + as the rh factor; a person with BO or BB will have type B blood.
In other words neither can be O. And BOTH cannot be A or B or negative. As long as one carries A (by either being A or AB) and one carries B (by being either B or AB) a child can have AB blood. Negative is recessive therefore as long as one parent has positive blood it is fine. :)

∙ 14y agoWell A is a dominant trait meaning that both parents could have given A, or one parent is A and the other is O, O is recessive meaning to get O both parents have to give O. Now this is where it gets confusing a parent can have genotypes from their parents and if a person is O and has a mom that is A the person's blood type could be OA, when having a child the parent could give either A or O. So It's really hard to say, but I'd say you both are A, or one is O and one is A. since B is also dominant and if you were to have a child together and the dad was a and the mom was B the child would be AB. hope you inderstand it's really confusing.

∙ 13y agoBoth parents could be A ( heterozygous )
Both could be B ( heterozygous )
or both could be O
or one is A and the other is B ( heterozygous )
to have a negative baby
both should be negative
or both is positive ( heterozygous ) but in this case the chance of having a negative baby is LOW.
one is Positive ( heterozygous ) and the other is negative, also the chance to have a negative baby is LOW.

∙ 14y agoOne or both of the parents must have type negative blood (--) or type positive (+-) blood. Neither parent can have type positive (++) blood.
ABO blood type doesn't matter with +/-

Can o positive blood group and o positive blood group parents have child?
Yes, blood type has no bearing on weather or not the parents can have a child
Can O positive blood group and B positive blood group parents have child?
Yes, blood type has no bearing on weather or not the parents can have a child
What blood GROUP do parents have to have a child with type o negative blood group?
at least one of them have negative group.
Is it possible for a baby to have a different blood type then the parents?
It is possible if your parents have different blood types. Example, if your father is A with a recessive O, and mother is B with a recessive O, you could easily land up with a O blood group. However, an AB father can have only an A, B or AB child depending on the mothers blood group, but surely NOT 'O.'
Can parent both blood type o positive have a child with b positive blood type?
No, an O-group set of parents can never have children with blood that is not also O-group. They lack the necessary B allele.
Can O positive blood group and B positive blood group parents have child?
Yes, blood type has no bearing on weather or not the parents can have a child
Can o positive blood group and o positive blood group parents have child?
Yes, blood type has no bearing on weather or not the parents can have a child
What blood GROUP do parents have to have a child with type o negative blood group?
at least one of them have negative group.
Can both parents with blood group B have a child with blood group O?
Type your answer here... yes
If husband is type ab and the wife is type a can they have a child with type o blood?
Simple answer - NO. The child will always have the same blood group as one of its parents.
If a child does not have either one of his parents blood type is he there child?
yes. If one parent has blood group A (as in genotype AO) and the other has blood group B (as in genotype BO) can have a child with blood group O
If a father and mother of a child are o positive what blood group would the child be?
The child has to get his/her blood type from the parents. So therefore if both parents are O type then the kid has to be O type. This makes sense to me.
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 parents both blood type O have a child with A negative blood?
No, At least one parent would have to be an A (or an AB) for a child to have group A blood.
Can O and A blood group parents have child?
Yes,but if the baby is blood type B then there is ABO incompatibility.
How does a A blood type mother AND a father have a -0 blood type child?
The mother and father both have heterozygous alleles for the blood group A. The blood group A can have the alleles AA or AO, when both parents are AO, there is a one in four chance that the child will have blood group O as this blood group is recessive.
Both parents are blood type A what will the child be?
The blood group of the child will be either A or O. The baby's blood group is always determine by the genotypes of his/her parents. Lets see following conditions: 1) Both parents have AA and AA blood type (both homozygous dominant): Their child would always have type A blood group (AA). 2) If any one of the parent has genotype AA and other AO ( i.e. one homozygous dominant and other heterozygous dominant): Their child would have type A blood group (AA or AO). 3) If both parents have genotypes AO ( both heterozygous dominant): Then their child would have either blood group type A or O ( i.e. AA /AO /OO). Just carry out the crosses by forming the gametes of the parents and check their recombination's. You will definitely understand this.
