Is it true that to have a child with O blood type both parents have to be O type?

No, this is not true. The child has to inherit two type O genes, however. Blood type is inherited as a co-dominant factor. For instance: Mom is A+, but her blood type genes are A and O. Because of the codominant nature of blood types inheritance, her blood is type A. Dad is O-. He has two type O genes. If, during fertilization, an ovum from the mother with type O gene combines with one of Dad's spermatozoa, the child will be type O. If an ovum with type A gene is fertilized, however, the resultant child will have type A blood. Same goes for mom who is A and dad who is B, so long as their genes are A/O and B/O, they can still have a type O child. If mom is A/O and dad is B/B, however, there is no chance the child will have type O. The child could have type B (B/O pairing) or AB, however.

Is t true that parents with blood type AB and O will reproduce abnormal child?
Not true, blood types do not make us normal or abnormal!
Can parents b positive and O positive have a b negative child?
Yes, that's True. for Rh- to come, both parents should be Heterozygous.
Does an Rh negative child require both parents carry at least one Rh negative allele?
Yes, that's True. for Rh- to come, both parents should be Heterozygous.
Is it true that if mother is B positive blood group and father is B positive blood group the child's blood group will be only B positive or O positive?
yes it is true that the child would have either B or O positive blood groups only. This is because the father may have the genotype OB if he is heterozygous and BB if he is homozygous. So is the case for the mother. Rh factor determines if the blood group is positive or negative. Since the parents are positive, so would be the child. Thus upon recombination, the only possible blood groups will be O or B.
If parents who already have a son decide to have a second child it will have an equal chance of being either sex?
True.
Can parents both blood type O have a child with B positive blood type?
It must have one of the true parents blood types.
Is it true that the blood of a child comes from the sperm from the father and not the mother?
No. The child is a unique mix of both of its parents.
Is it true that if both parents are AB and O blood types there will be a problem with the child?
no that's absolutly a mith ur fine
Is t true that parents with blood type AB and O will reproduce abnormal child?
Not true, blood types do not make us normal or abnormal!
If mother is A positive and dad is A positive what is the child's blood type?
My husband is A+ and I am O-. We have two children. Our daughter is O+ and our son is A+. A is dominant, O is recessive. + is dominant, - is recessive. Therefore in this situation it is possible to have children with O+, O-, A+, and A- so long as the father carries the recessive genes.
Is it true babys tell if your boyfriend is cheating on you?
Yes, the baby's DNA contains cromosones from both parents, there are 24 pairs in total, one from each parent in each pair. They take DNA from both parents, and the child and compare the parents with the child's.
Can parents b positive and O positive have a b negative child?
Yes, that's True. for Rh- to come, both parents should be Heterozygous.
Does an Rh negative child require both parents carry at least one Rh negative allele?
Yes, that's True. for Rh- to come, both parents should be Heterozygous.
A child has sickle-cell disease (ss) but neither parent is ill What must be true of her parents genotypes?
The parents are both recessive (Ss) for sickle cell anemia.
If a child has sickle-cell disease (ss) but neither parent is ill. What must be true of he parents' genotypes?
The parents are both recessive (Ss) for sickle cell anemia.
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.
A child has sickle-cell disease (ss) but neither parent is ill. What must be true of her parents and rsquo genotypes?
The parents are both recessive (Ss) for sickle cell anemia.
