This means that each child born to these parents has a 1 in 8 chance of having a baby with an O blood type. Each of their children also has a 3 in 8 chance of an A+, a 3 in 8 chance of an O+, and a 1 in 8 chance of an A-.

Can an O+ parent and an A+ parent have an O child?

One parent with A and another with B can father a child with blood types A, B, AB or O. If one parent has A and another has AB, they can father a child with either A, B, or AB blood types. If one parent has A and another has O, they can father a child with either A or O blood types.
Rh incompatibility in pregnancy
Problems can arise when the mother has Rh- and the baby has Rh+. This blood type mismatch is often referred to as Rh incompatibility. This discrepancy does not cause problems for the first pregnancy. But it can cause problems in later pregnancies.
But it’s technically possible for two type O parents to have a child with A or B blood and maybe even AB (although this is even less likely). In fact, a child can get almost any type of blood type if you account for the irregular exceptions.
Yes, it is definitely possible. In this case, the most likely explanation is that dad carries Rh and mom carries type O blood. What happened was that dad and mom each passed both an O and a Rh negative to the baby. p>
The correct option is: d Rh+ male and Rh– female Explanation: Rh factor is a protein found in the blood. A person with Rh factor in their blood is referred to as Rh positive, while a person who does not have this protein in their blood is referred to as Rh negative. A marriage between Rh negative female & Rh positive male.
When an expectant mother and father are neither positive nor negative for the Rh factor, it is called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh positive blood inherited from the father.
Scientists have found that a woman’s blood type can affect her chances of conceiving. Individuals with Blood Type O may have difficulty conceiving due to a lower egg count and poorer egg quality, while individuals with Blood Type A appear to be more fertile.
If the father’s Rh factor genes are + + and the mother’s + +, the baby will have one + from the father and one + from the mother. The baby will be ++ Rh positive. If a father’s Rh factor genes are + + and the mother’s – -, the baby will have a + from the father and a –gene from the mother.
A child with blood type O can have parents with blood type A, B or O, but not with blood type AB. Conversely, if two parents both have type O blood, all of their children will have type O blood.
What is the rarest blood type? AB Negative is the rarest of the eight main blood types – only 1% of our donors have it. Although rare, the demand for AB negative blood is low and we have no difficulty in finding AB negative blood donors.
O-positive red blood cells are not universally compatible with all types, but they are compatible with all positive red blood cells (A+, B+, O+, AB+). Over 80% of the population has a positive blood type and can obtain O-positive blood. This is another reason for the high demand.
Myth: O-negative blood is the rarest blood type
Contrary to popular belief, O blood is not the rarest blood type. It is estimated that 7% of the population has O- blood type, while only 1% of the population has AB blood.
Although your blood and your baby’s blood do not typically mix during pregnancy, a minimal amount of your baby’s blood and your blood may come into contact during delivery. If you have Rh incompatibility and this happens, your body may be making Rh antibodies to Rh factor.
