25% for blood type O, 50% for blodd type AB, and 25% for A.

Wiki User
∙ 13y agoAbout 50%, the child will have get an O type from the father, and either an A or an O from the mother. The result will be a child with either type A or type O blood.

If a half-blood marries a pure-blood what blood will their child be?
Half-Blood.
If the mother is O positive and father is AB negative what type will baby have?
The O blood type is always recessive; A and B are codominant and dominant to O. The O blood type is represented with both O alleles, and the AB blood type is represented with one A and one B alleles. The child will either have a genotype AO or BO, but the blood type will be expressed as A or B. This cross can be demonstrated easily with a Punnett square. For the Rh factor. This is dependent on the mother's genotype since the father carries the recessive alleles. The Rh factor for both homozygous and heterozygous dominant cases is positive. Thus, if the mother is heterozygous there's a 25% chance that her child with have be Rh+. If she is homozygous dominant, her children will always be Rh+. This can also be demonstrated with the Punnett Square.And that is the answer
What are the possible blood types of a child if a woman with Type A- blood marries a man with B?
It depends on the genotype of the parents: If they are AO and BO the child could be all of the 4 ABO-Bloodtypes: AO (= bloodtype A) BO (= bloodtype B) AB (= bloodtype AB) OO (= bloodtype O) If they are AA and BB the child could only be bloodtype AB If they are AO and BB the Child could be AB, or B (BO) If they are AA and BO the child could be AB or A (AO) In short, when the genotype is not given, the child can have any of the ABO-Bloodtypes
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.
Are all children of same parents the same blood type?
of course they can, it doesnt mean that if you dont have the same blood type as your siblings, your adopted or something. if your parent's blood types differ from each other there is a huge tendency that the sibling's blood types are different from each other. for exaple your father is a heterozygous A while your mother is a heterozygous B.. their children's blood types can be AB, and an O can also be one of the possiblities.. if its too complicated to understand then you can just learn it from your genetic lessons in biology..
You are A your wife is O- what will the child be?
Your child can be anything. It doesn't really matter what the parents are. Anything that runs through the family your child can be. The chances of being an O are very small but it is still possible. It depends on whether or not you are homozygous or heterozygous A. All O blood is genetically homozygous. If you are blood type AO then there is a 50% chance of Homozygous O (OO) and 50% chance of heterozygous A (AO). If you are Blood type AA then there is a 100% chance of heterozygous A (AO)
If a half-blood marries a pure-blood what blood will their child be?
Half-Blood.
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.
Can a a blood group father produce an o type child?
An A blood group father can have an O type child. If he does, then he is heterozygous for type A.
A child is born with type AB blood what blood must the parents have?
The most likely blood type for the child is A positive - but A negative, O positive and O negative are also possible depending on the genotypes of the parents. If both parents are heterozygous AO, then the child could have either A or O type blood. If either parent is homozygous, AA, then the child must have blood type A. If the parent with positive blood is heterozygous, Dd (+-), then the child could have either positive or negative type blood. If they are homozygous, DD (++), then the child must have positive type blood.
If heterozygous type a father is married to a heterozygous type b mother?
Assuming a and b are referring to blood types... The father will have the genotype Ao The mother will have the genotype Bo Their offspring will be 1AB:1Bo:1Ao:1oo. This means the child has an equal chance (1/4) of being blood type A, B, AB and O.
If both parents have A blood type can they have a child with o blood type?
Yes. Both parents could be heterozygous, that is AO, and pass on the O to their child.
What problems will child suffer if a boy with blood group A positive marries a girl with blood group A negative?
The child will suffer from rh incompatibility.
Can a child be O negative is mother is A negative and father is O positive?
Yes, if the father is heterozygous for blood group A and heterozygous for positive rh factor.
What will be the blood group of ababy when father has b plus blood group and mother has o plus blood group?
The child can be A, B or AB. The only group the child shouldn't be is O. You receive one allele from each parent. Each group actually has two places. Therefore the B is actually BO or BB. If child is A, this means the mother's group is BO. Now mix and match. Mother gives B Father gives B Child is B Mother O Father B Child B Mother O Father A Child A Mother B Father A Child AB Mother B Father B Child B The Rh factor is similar but not so easily determined. While it also has two places, the + can hold a - for it's second placement +- For instance, my mother is AB Neg but all of her children are Pos. This means her Rh factor must be -+. Hope this helps.
What are the possible blood types of a child who's parents are both heterozygous for B blood type?
Only B and O are possible
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
