If the parents are Type A and Type O could they have children with Type B blood?
Wiki User

We are looking for the possible blood types of a baby.
Parental information:
- Mother type A -- can be AA or AO = contributes the A or O gene
- Father type O -- can only be OO = contributes the O gene
- Baby is type AO
- Baby is type OO
HOWEVER: There is more to ABO blood typing that just the ABO gene.
There is also an inhibitory gene that will change any genotype into the phenotype O.
Therefore a person with genetically AB blood can be tested as having Type O.
If the Type O parent has the inhibitory gene affecting his Type B or AB blood, then the Type B baby is definitely possible.

Can 2 type o blood types have a blood type a child?
Parents of blood type O can only have children with blood type O. Because type O is recessive, you know that the parents are homozygous O.
Can a baby have the mother's blood type?
The two AB parents could have any of an A, B or AB, but not O.The two A parents could have either A or O children, but not B or AB.The two B parents could have either B or O children, but not A or AB.The two O parents could only have O children; they cannot have have A, B or AB.If both parents have rhesus-negative blood, so will their children. If both have positive, the child might be either.
What blood type do children get mothers or fathers?
You don't get just one or the other. For example: If your blood type is AB, either of your parents could have A, B, or AB. Another example: I have O and my husband has O. All of our children will have O, because O doesn't combine with A or B.
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.
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..
Could two parents that have blood type A have children with blood type O?
No, unless they adopt.
Could two parents that have blood type 0 have children with either blood type A or blood type B?
No way...
How can a child's blood type be b positive if mom is b positive and dad is a positive?
You could have several children with different blood types. you get your blood type from either parents or even grand parents.
Can a child with b negative blood have parents with o positive?
Only if he's adopted. Parents with a + blood type can have children with a - blood type, but parents with an O bloodtypes can only have O type children together.
Can parents with o blood type to have a child with b blood type?
If both parents are type O blood they will only have type O children
If both parents are both type a positive blood what blood type will their children be?
blood group "A" or "O".
Will parents with a positive blood type have children with a positive blood type?
There is 50% that children will be of negative blood type if parents are heterozygous positive. 25% if one parent is homozygous and other heterozygous. 0% if both homozygous.
Can 2 type o blood types have a blood type a child?
Parents of blood type O can only have children with blood type O. Because type O is recessive, you know that the parents are homozygous O.
Should children have same blood type as parents?
No. Often a child can have a completely different blood type from their parents or even the same. It really depends on their genetics.Some combinations of parents are unable to get children with certain blood types - assuming no mutations occur.Regarding the AB0-system:If both parents have blood type 0, all their children will have blood type 0.If both parents have blood type A, no children will have blood type B or AB.If both parents have blood type B, no children will have blood type A or AB.If both parents have blood type AB, no children will have blood type 0.Of course you can be more specific if you know the parents' genes.
Can two parents with o negative blood have a baby with o positive?
Each person receives an A, B, or O gene from each parent. In this system, the A and B genes are co-dominant and the O gene is recessive. Thus, a person whose genetic type is either AA or AO will have blood type A, those with genetic type BB or BO will have blood type B, and only those genetic type OO will have blood type O. This means that a child with type O blood could have parents with type A, type B, or type O blood (but not with type AB). Conversely, if two parents both have type O blood, all their children will have type O blood. Another medically important blood type is described in the Rh system. These genes were first discovered in the rhesus monkey, hence the designation Rh. The Rh system is actually far more complex than the ABO system in that there are 35 different possibilities that one could inherit from each parent. These, however, are roughly grouped into positive and negative types. In this system the positive are dominant over the negative. If your genetic type is ++ or +-, your blood type will be Rh positive. Only if your genetic type is -- will you be Rh negative. This means that if both parents have Rh+ blood with the +- genes, they could have children who are ++, +-, or --. In other words, their children could be either Rh positive or Rh negative. Children who are Rh negative can have parents who are either Rh positive or Rh negative. Two parents who have O positive blood could easily have a child who is O negative. In fact, most children who are O negative have parents who are positive, since the +- combination is so much more common than the -- combination.
If you have O positive blood and your panter has O neg. blood what would your kids have?
It is hard to tell if your blood type is dominate and your partners blood type is recessive them the child could have O positive blood, but if your blood type is recessive and your partners blood type is dominate then the child could have O negative. Sometime the child could get a completely different blood type eve if their parents do not have it. There is no way you can tell.
What are the chances of having two kids that have the same trait?
This depends on the genetics of the parents. Simple blood group genetics lends itself to this concept. If both parents are AA then all children will be AA The most common blood groups are A, B and O Types A and B are dominant over type O blood. Types A and B combined produce an intermediate AB blood type. If the parents are heterozygous AO and BO respectively their children could be phenotypically A, B, AB or O (genotypes would be AO, BO, AB or OO). AA AO parents only A type children AO AO 3/4 A type, 1/4 O type BB BO parents only B type children OO parents only O type children AA and BB parents all children would be AB AO and BB parents children AB or B only AA and BO parents children AB or A only AB and AB parents children AB AA or BB
