Several ways, and here is why.
First, some definitions. PHENOTYPE is how the trait is physically displayed in the person, so a person's blood type is actually their phenotype. GENOTYPE is the pair of genes that a person carries that determines their phenotype. A RECESSIVE gene is one "trumped" by a DOMINANT gene in the genotype; for blood typing, O is the recessive gene and A and B are dominant. For a person to show the recessive phenotype, they must carry BOTH recessive genes. So, in order for the baby to be type O it must carry two O genes and have genotype "OO".
The baby will inherit one gene from the mother and one from the father and, as explained above, both must be O genes. Obviously, a parent with type O blood will pass on an O gene, this is all they can do. But there is also a chance a parent with type A or type B blood can pass on an O gene. This is because a parent with genotype AO will be type A (remember, the A gene is DOMINANT) but can still pass on the O gene. Same with a parent having genotype BO. Only a parent with AB blood cannot have a type O child since they must pass on the A or B gene (in other words, they have no O gene to give).
What else can I help you with?
Can a mother of 0 negative blood type and a father of A negative blood type have a child with AB blood type?
No they cannot. They can only have a child with type A or type O blood.
What is the likelihood of a child's blood type being determined by the blood types of their parents?
The likelihood of a child's blood type being determined by the blood types of their parents is high, as blood type inheritance follows specific patterns based on the parents' blood types.
Is there a posibility to have a child that is blood type -A A couple who are blood type B and blood type O?
No. It is not possible for a child to have A if the parents are O blood type. If both parents have type O blood, then their children will also have type O blood. However, two parents with type A or type B blood (both the same or one of each) can sometimes have a child with type O blood. That is because the gene for type O blood is recessive. But they must carry the O type. However, two parents with type AB blood can have a child with type A, type B, or type AB blood, but cannot have a child with type O blood.
If the parents are both blood Type A could they produce a blood Type AB child?
No, parents who are both blood type A cannot produce a child with blood type AB because blood type AB is the result of inheriting one A allele and one B allele. Both parents would need to pass on the B allele to the child in order for them to have blood type AB.
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 a mother of 0 negative blood type and a father of A negative blood type have a child with AB blood type?
No they cannot. They can only have a child with type A or type O blood.
Can a A negative and B negative parental blood types produce a A positive child?
No. They could have an A- child, but not A+.
Can a blood group have a child with another a blood group?
Yes of course all blood types produce the same species of genes it just will help determine what blood type your child will have.
How can you get your child's fathers blood type without him knowing?
You can limit what possible blood types the father has if you know the mother's and the child's. For example, if the child is type O, the father cannot be type AB, and if the child is type AB, the father cannot be type O.
Can a women with A negative and man with B positive produce child?
Yes. Blood types do not make parents incompatible.
What two blood types from parents produce blood type A in child?
Parents must be blood type A or O. Any other blood type will not result in a sole A type child. It might result in several other combinations though, which are not relevant to this question.
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 parents with o blood group and a blood group produce a- Blood group child?
Yes, parents with O and A blood types can have a child with A- blood type. The child would inherit one A allele from the parent with A blood type and one negative Rh factor from the parent with O blood type.
When O positive man marries an A Negative girl will their child have health problems?
Mixing blood types will not any impact on the health of a child, only the resultant inherited blood type. This particular mix will produce a child with an A pos or A neg or O pos or O neg blood group.
What is the likelihood of a child's blood type being determined by the blood types of their parents?
The likelihood of a child's blood type being determined by the blood types of their parents is high, as blood type inheritance follows specific patterns based on the parents' blood types.
Can Two o positive parents have a ab positive baby?
No, two O positive parents cannot have an AB positive baby. Inheritance of blood type follows specific patterns, and a child cannot have a blood type that is not possible based on the parents' blood types.
Can a O mom produce child with ab dad?
Yes, the daughter will be A. Yes, the daughter will be A.
