If a man with type a blood marries a woman with type b blood their child has type o blood what are the genotypes for these individuals?

In order to have type O blood you must have two O alleles (OO). Both the child and the mother must therefore have an OO genotype. The Father must have contributed one O allele and could be one of 3 genotypes: AO, BO, or OO.

∙ 10y agoWe are looking for the possible blood types of a FATHER.
Parental information:
- Mother type O -- genotype OO - will contribute only an O gene
- Baby type A --genotype is AO with the A contribution from dad
- Baby is type AO
- Father may be AA = Type A
- Father may be AO = Type A
- Father may be AB = Type AB
- Father is NOT BB, BO or OO = Types B or O

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.
Man with blood type B marries a woman with blood type A and their child is blood type O what is the porbabtility their next child will be blood type AB or B?
Twenty-five percent for any of the four possibilities.
If one parent has A-blood and the other has A plus blood is it possible for the child to have O-blood?
Yes! The genotypes of the parents can only be "OO" (means two O genes) so both of them cannot give a "B" gene to the child
What is the only genotype that will produce O type of blood?
The gentotype is ii that will produce blood type O. The allele i is recessive, so both parents must have at least one i allele, and the child must be ii (double recessive) to be blood type O. The parents' blood types do not have to be type O- the genotypes Ai (blood type A, as A is dominant), and Bi (blood type B) can produce blood type O offspring, as long as the child inherits the i allele.
If one parent has a blood of b negative and the other o positive?
The child's blood could be B+, B-, O+ or O- depending partly on the exact genotypes of the parents and partly on random chance.You might want to have a look at this answer in Answers.com for more details. It explains all about blood types and their genetics.What_happens_if_both_parents_of_a_child_are_A_negative
If a half-blood marries a pure-blood what blood will their child be?
Half-Blood.
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.
If the mom is o plus blood and so is the child what blood types can the father have?
The child inherits one allele from each parent for their blood type. You said that the mom is o+ and so is the child. Therefore: The father cannot have the following blood type genotypes: AB+, AB-, AA+, AA-, BB+, or BB-. The father's blood type genotypes can be: Ao+, Ao-, Bo+, or Bo-.
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.
How could two parents with blood types a and b have a child with o?
If the parents had the genotypes AO and BO, then they could have a child with Type O blood (there would be a 25% chance of this occurring).
Man with blood type B marries a woman with blood type A and their child is blood type O what is the porbabtility their next child will be blood type AB or B?
Twenty-five percent for any of the four possibilities.
Will two negative A blood type parents always have an A negative child?
Not necessarily. It could result in a O neg baby depending on their genotypes.
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 does dominant means?
Co-dominance happens when two genotypes are expressed at the same time. For example, one parent can have blood type A and one parent can have blood type B and together produce a child with blood type AB. If two parents have the blood type AB, the child has a chance of being mentally ill.
If one parent has A-blood and the other has A plus blood is it possible for the child to have O-blood?
Yes! The genotypes of the parents can only be "OO" (means two O genes) so both of them cannot give a "B" gene to the child
A woman who has type A blood marries a man with type B blood Their first child has type O blood What are the expected genotypic frequencies of all possible offspring that the parents can have?
ii, IAi, IBi, IAIB
What does co dominance mean?
Co-dominance happens when two genotypes are expressed at the same time. For example, one parent can have blood type A and one parent can have blood type B and together produce a child with blood type AB. If two parents have the blood type AB, the child has a chance of being mentally ill.
