I don't believe so.
Yes, two Type O parents can create a healthy Type O baby. If the mother is Type O negative, and the first baby is positive, then there may be a danger to future positive babies because, during the first pregnancy, the mom's body may produce antigens to the positive blood type. This scenario may be why blood tests are taken when couples marry. A doctor should be consulted.
The baby with type A blood goes to the parents who are type A heterozygous and type O, as it is the only combination that can produce a type A baby. The baby with type O blood goes to the parents who are type A homozygous and type O, as they could not have a type A baby.
A blood type is coded in two parts, one from each parent. To be type B a person can either be BB or BO, while a person with type O must be OO. So for the baby to be type, it must have received an O from both parents. If the parents both have to be type b, then they must both be BO.
The baby will either be blood type O or Type A
Blood type: O
If with A + and O + Baby can have : A + or O + If with A + and O - Baby can have : A +, A-, O +, O - If with A - and O + Baby can have : A +, A-, O +, O - If A - and O - Baby can have : A + or O -
The baby can have either O- or O+ blood type.
A person who is blood type AB has to be genotype AB. A person who is blood type O has to be genotype OO. So if a person who is AB mates with a person who is O, they cannot have a baby with type O. They could have an A or a B, but not O or AB.
A person cannot have blood type A and O at the same time. Although they can have one allele for each, Ao - but this person would have blood type A. If you are asking whether a mother and father with types A+ and O+ can have a child, the answer is yes. This child will be either type A or O depending on the genes of the parent with type A blood.
If a mother who is blood type A and she donates her A allele to the baby, then it could definitely be type A.
If the mother and father are both type O, the baby cannot be type AB.
The baby's blood type would either be type A or type O. The father (phenotype A) could have an underlying genotype of either AA or AO. Therefore, the baby could have either type A (AO - with A from the father and O from the mother) or type O (OO - with O from the father and O from the mother) blood.
