For example, two O blood type parents can produce a child with only O blood type. Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type.
Two O parents will get an O child nearly all of the time. But as with anything in biology, there are occasional exceptions to this rule.
Rh incompatibility occurs when the mother's blood type is Rh negative and her fetus' blood type is Rh positive.
If mom passes her O and so does dad, then the child will be OO which is O type blood.
Theoretically yes, but it would be extremely rare. Two O parents will get an O child nearly all of the time.
A. Before I delve into the science, let me quickly stop any tongues that might be wagging if you are asking about a paternity debate: Yes, two O-positive parents could have any number of O-negative children. In fact, according to the experts, most children who are O-negative have parents who are O-positive.
Only 7% of the population are O negative. However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood.
Type O positive blood is given to patients more than any other blood type, which is why it's considered the most needed blood type. 38% of the population has O positive blood, making it the most common blood type.
In this case, the most likely explanation is that dad is a carrier for being Rh- and mom is a carrier for blood type O. What happened was that dad and mom each passed both an O and an Rh negative to the baby. The end result is an O negative child.
Different blood groups rarely cause any problems, but your rhesus factor may affect future pregnancies if you're rhesus-negative and carrying a rhesus-positive (RhD-positive) baby in this pregnancy. If some of your baby's blood mixes with your blood during pregnancy or birth it can put later babies at risk.
A person having Rh factor in blood is called Rh positive whereas that who does not carry this protein in the blood is called Rh negative. Marriage should be avoided in between Rh negative female & Rh positive male. This can be fatal for the mother as well as the baby of such parents.
When the blood of an Rh-positive fetus gets into the bloodstream of an Rh-negative woman, her body will recognize that the Rh-positive blood is not hers. Her body will try to destroy it by making anti-Rh antibodies. These antibodies can cross the placenta and attack the fetus's blood cells.
Those with blood type O may struggle to conceive due to a lower egg count and poorer egg quality, while those with blood group A seem to be more fertile.
A baby may have the blood type and Rh factor of either parent, or a combination of both parents. Rh factors follow a common pattern of genetic inheritance. The Rh-positive gene is dominant (stronger) and even when paired with an Rh-negative gene, the positive gene takes over.
Yes, you can.
People with type O blood will react against type A, type B, or type AB blood. People with type AB blood will not react against type A, type B, type AB, or type O blood.
O positive blood can't be used universally because it has the Rh factor, but it is compatible with all positive blood types including O+, A+, B+, and AB+. Since over 80% of the population has a positive blood type, type O positive blood is in high demand.
So, the progeny formed if both parents are of O blood group is O. The Rh factor can be positive in heterozygous state and also in homozygous state. So, there can be possibility of being both Rh positive and Rh negative. The blood group can be both O positive or O negative.
Blood groups in Australia
According to Australian Red Cross Lifeblood, the percentage of blood group frequency in Australia is: O positive - 40% O negative - 9% A positive - 31%
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
People with type O blood enjoy a slightly lower risk of heart disease and blood clotting, but they may be more susceptible to hemorrhaging or bleeding disorders.
