Blood Type A is dominant to Blood Type O. That means that a person with genotype AA and a person with genotype AO will both have Type A Blood, while a person with genotype OO will have Type O Blood. If both parents have blood type AO, they will both have Type A Blood, but their child will have a 25% chance of having Type O blood. The blood type ratio of their children will be 25% AA (Type A Blood), 50% AO (Type A Blood), and 25% OO (Type O Blood).
What else can I help you with?
If you have o negative blood do your parents have o blood too?
They could, but they don't need to. Both of your parents must have at least one O allele, meaning neither can have type AB blood. They must be either BO, AO or OO to produce a child with type O blood.
Can O positive and A negative have baby?
yes
What blood types would produce a b negative child?
There is no single answer to this question. First, how does the child get type AB? The child needs to get an A gene from one parent and a B gene from the other, simple as that. This means neither parent can be type O because they would not be able to pass on the A or B gene (that is what O means, the absense of the A or B gene). If one parent is type A, the other must be B or AB. If one parent is B, the other must be A or AB. Also, both parents can be AB. In all cases, one passes on the A gene and the other passes on the B gene, that's it.Second, for the Rh factor (the positive and negative), the negative trait is recessive. This means the child must receive a negative gene from BOTH parents to display the negative phenotype. So the parents can be ANY Rh type. Why? Because it is a PAIR of genes, the GENOTYPE, that determines the trait. In the parents, they can be genotype +/- or -/+, meaning they have both the positive and negative gene and they can pass on the negative gene, but they will be POSITIVE Rh because that is the dominant trait. Of course, either parent could also be negative, -/- genotype, and they would certainly pass on the negative gene. So, you see, you cannot definitively type the parents in this case.
Aaron has blood type O. Can either of his parent have blood type AB?
no, blood type AB has gennotype IA,IB while blood type o has the genotype II. Each of his parents passed on an allele,So neither could have blood type AB
Can 0 positive parents born an A positive child?
No, two parents who are both blood type O positive cannot have a child who is blood type A positive. Blood type inheritance follows specific rules, and in this case, it is not possible for two O positive parents to have a child with blood type A positive.
Can parents with B negative and AB positive have a child with O negative?
No, parents with B negative and AB positive blood types cannot have a child with O negative blood type. The O blood type is inherited from both parents who must pass on the O allele to the child. Since neither parent in this case carries the O allele, they cannot have a child with O negative blood type.
Can a child be O negative if both parents are O positive and three of the grandparents are O positive and one is B negative?
It is possible as the Rhesus factor is a dominant trait. So, even if the parents have only one allele for the factor, there is a 1/4th chance that the child could get neither allele from the parents and end up as O negative.
What blood type will child have if both parents are o negative?
If both parents are O negative, their child will also be O negative. This is because O negative is a recessive blood type that requires both parents to contribute an O negative allele for the child to have O negative blood type.
Can O negative parents have an O positive child?
If they are both O negative, no, the child will be O negative.
If you have o negative blood do your parents have o blood too?
They could, but they don't need to. Both of your parents must have at least one O allele, meaning neither can have type AB blood. They must be either BO, AO or OO to produce a child with type O blood.
What blood GROUP do parents have to have a child with type o negative blood group?
For two parents to have a child with type O negative blood group, both parents must have at least one O and one negative Rh factor allele. The possible parental blood group combinations could be O negative x O negative, O negative x O positive, A negative x O negative, or B negative x O negative.
O negative plus o negative equals what bloodtype?
If both parents are O- then the child will be O-.
Can parents with o negative blood and b negative blood have a child with a negative blood?
yes it can be possible too as the parents is already with an o blood group..
Can a child be O negative if the parents are O positive and their are three grandparents who are O positive and one is B negative?
Yes.
If both the parents have O Negative blood can a daughter be O Positive?
No
Can parents who have B negative and O positive blood types have a child with O positive blood?
No, they will have a O negative child.
Can parents with o plus and o negative group can have a child with b plus blood group?
normally they have "o" plus or negative.
