The gene for blood type O is recessive. The mother can only have the phenotype O if she has the genotype OO.
The gene for blood type B is dominant, the father has the phenotype B, but can have the genotype BB or BO.
If the father is genotype BB, the child will be B + O = BO genotype; hence B phenotype.
If the father is genotype BO, the child can be B + O = BO genotype; hence B phenotype (50% chance). Or O + O = OO genotype (O phenotype, 50% chance).
* Phenotype = displayed trait that can be found with a simple blood test.
* Genotype = genetic make up (one part from each parent), this requires a DNA test to be confirmed; however, it can sometimes be deduced by logic.
What else can I help you with?
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 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.
If a mother has a positive blood and father has o positive blood can the baby have ab negative blood?
it it possible if someone from either parents' family has had it or haves it because of genes
What blood type do the parents have to be to make an A positive baby?
One of the parents must be A or AB, and one must be positive.
A positive father a positive motherwhat is your child's blood type?
If you're talking RH Factor (i.e., you are O-Positive, and your wife is O-Positive) then the baby will be O-Positive. If both the RH Factors are positive, then the baby will be positive.
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 two parents with o positive blood have a baby with b positive blood?
Another has said: no chance. One of the parents must be b positive.
Can a baby be born with positive blood if both parents have negative blood?
No, it is not possible.
Can two parents with AB positive blood harm the baby?
No, it will not.
If two parents have A positive blood can the baby have O positive?
yes it is possible, blood groups do not work that way.
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 blood type can a baby be if the father and mother are both type B positive?
A baby can be any blood type that is possible through the combination of the parents' genetic material. In this case, the baby could be blood type B positive like the parents, or it could be blood type O positive if both parents are carriers of the O blood type gene.
Can parents with AB positive and A negative blood have a baby with 0 negative blood?
Yes
When Parents with b positive and o positive blood have baby with o negative blood group?
I'll wait for you to ask the question. Positive parents can have a negative baby as positive is dominant so they may both have one positive and one negative gene and the baby gets the two negative genes.
If one parent has A positive blood and the other had A positive blood what type will the baby have?
The blood type would be A positive.
If both parents have a blood type of O positive will the baby have the same blood type?
The baby can have either O- or O+ blood type.
Can a baby with ab positive blood group come from parents with o positive blood group?
Yes! Yes indeed. Does the baby look like the mailman? No. O parents can't make AB babies.
