If both parents are O, the children will definitely be O. The O type is recessive--both alleles must be O for the child to be O. Since both parents are O, we know the union contains four O alleles--hence any child will be O. The Rhesus factor is the question. The Rh positive allele is dominant, so an Rh positive person can carry either one or two of them and still be positive. If one parent carries two Rh positive alleles, any child of theirs will be Rh positive. If both of them carry an Rh negative allele, there's a 25 percent probability the child will inherit two Rh negative alleles and be Rh negative. (The other choices are the child inherits two Rh positive alleles, at 25 percent probability, and the child inherits only one Rh positive allele, at 50 percent probability because the Rh positive allele could come from either parent.)
What else can I help you with?
Mother o positive father o positive and child also o positive is possible or not?
Yes, it is possible. Parents who are O positive may have children who are O+ or O-, depending on the parents' genotypes.
Can two parents with O positive blood have a a positive baby?
No, this can't happen, if two parents are O blood type, all kinds will be O.
What is the chance of both parents 0 positive having three children O positive and one A positive?
Assuming both parents are O positive (OO), they can only pass on the O allele. However, since one child is A positive, it means that one parent has the A allele (AO). This scenario is not possible with two O positive parents genetically. Therefore, the chance of both O positive parents having three O positive children and one A positive child is not genetically feasible.
Can two parents with O positive blood have a A positive child?
No, it is impossible to get an A-type from two O-types.
Can two parents with the O positive blood type with O blood positive type as well are they compactible?
There are no limitations on compatibility of parents based on blood type. Two O positive parents may have a child without any special concerns.
Can o positive and o positive have b positive baby?
No, two parents with O type blood cannot have a child with B type blood. This is because O is recessive - meaning in order to have type O blood, you need to have two O alleles. Therefore if both parents have O blood, all their children have to have O type blood. In order to have a child with B type blood, at least one parent needs to have B or AB type blood - in order to donate the B allele to the child.
Can two parents with blood type A positive have a child with O positive blood type?
Yes, if both parents have the genotype AO, then the child can have the O from both parents, phenotype O
Can parents with b negative blood have a child with o positive blood?
If both parents are B- they can only have children who are B- and O-. One would have to be positive in order to have a child with positive blood.
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.
O neg and O pos parents what happens to children?
If both parents are O negative and O positive, their children may inherit various blood types depending on their parents' genotype. However, all children will carry at least one O antigen in their blood type. The parents could have children with blood types O negative, O positive, A negative, A positive, B negative, B positive, AB negative, or AB positive.
Can a dad have a positive and mom have b positive?
I'm not sure what you mean by this but as for blood type, there's no reason two parents with different blood types can't have children. The children would have AB or O type blood depending on the recessives of the parents.
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.
