If both parents are O+ve, it means they have i allele, which is a recessive allele. For a person to have A+ve blood group, IA allele should be present. But in case of both parents being O+ve, there is no possibility that either of the parents carry the IA allele since it is a dominant allele. Thus the child would have to be O+ve.
What else can I help you with?
Can a child with o positive have a parents with a positive?
Yes, one or even both of his parents can be A positive.
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 parents b positive and O positive have a b negative child?
Yes, it is possible for parents with blood types B positive and O positive to have a child with blood type B negative. This can occur if the parents are both carriers of the negative Rh factor and pass it on to the child.
Can parents with both negative blood parent a positive child?
absolutely. as long as one of the parents is positive, the child can be positive. and if one parent is A the other B, the child can be A, B, AB or O depending on the parents' other alleles. so the child can definitely be A or B positive, but also A negative, B negative, AB negative, AB positive, O positive or O negative.
Can parents that are both a negative have an ab positive child?
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
If both parents have o positive blood how can the child have o positive L blood?
if both parents have positive o blood their child must have positive o blood
If both parents are O positive can they have a child that is A positive?
No. If both parents are type O, the child will be O. If both are A, the child can be either A or O. If both are B, the child can be either B or O. If both are AB, the child can be A, B, or AB (but not O).
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 a child have O positive blood if both parents are A positive?
Yes, if both parents are AO genotype there is a 25% chance of the parents producing a type O child. Since both parents are Rh positive the probability of an Rh positive child in at least 75%.
Can parents both blood type O have a child with a positive?
No. If both parents are type O, the child will also be type O.
Can a child with o positive have a parents with a positive?
Yes, one or even both of his parents can be A positive.
If both parents are A positive what usually will the child have?
A or O positive or negative
Can O negative parents have an O positive child?
If they are both O negative, no, the child will be O negative.
Can parents both both type blood o positive have a child with b positive?
yes
Can o positive and a positive parents have o negative child?
Yes. Since the Rh factor is recessive if both parents have a copy of the gene they can have an Rh negative child.
Is it possible for both parents with blood group o positive have a child with A positive?
yes
Is there any chance that a child can be o positive if both parents are o negative?
yes.
