Therefore, if both parents are B+, the possible outcomes for their offspring should be B+, B-, O+, or O-. Your brother therefore fits perfectly, but your blood type of A+ would break the conventional rules.
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. One parent with A and another with B can produce a child with A, B, AB or O blood types.
But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is even more unlikely). In fact, a child can get almost any kind of blood type if you consider the rule-breaking exceptions.
Can my baby blood group be different from its parents?
Is B+ blood type rare?
How rare is B positive blood? This means only 8% of donors have B positive blood. In total, 10% of people belong to blood group B, making it one of the least common blood groups.
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.
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.
– Are easily vexed and grow exasperated if things don't go the way they want them to go. – Usually have a strong drive to be the best at whatever they set their mind to doing; however, they also tend to neglect other tasks for the sake of whatever they are focusing on.
What happens when two blood relatives have a baby?
810 20 050). When parents are blood relatives, there is a higher risk of disease and birth defects, stillbirths, infant mortality and a shorter life expectancy. To have a child with severe diseases and disorders may cause heavy strain for the family in question.
Two B blood group parents can give their child either B or O blood group. One parent with A and another with B will give their child either A, B, AB or O groups. One parent with A and another with AB will give their child either A, B or AB groups.
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.
If you have type B blood, you can only receive type B or type O blood. You cannot receive type A or type AB blood. If you have type AB blood, you can receive all blood types.
Can a child have a different blood type than both parents?
Yes, a child is able to have a different blood type than both parents. Which parent decides the blood type of the child? The child's blood type is decided by both parents' blood type. Parents all pass along one of their 2 alleles to make up their child's blood type.
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.
All blood groups are compatible for marriages; the only concern should be the Rhesus factor antigens which may be a hindrance during blood donation/transfusion. It also affects the woman if she is negative and carries a Rh positive baby during pregnancy.
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).
Brothers and sisters don't always share the same blood type. The genotype of both parents plays a role in defining the blood type. For instance, children of parents with the genotypes AO and BO may have the blood types A, B, AB, or O. Thus, siblings do not necessarily have the same blood type.
O− blood, also called "universal donor," is perhaps the most valuable blood in the world because it can be transfused to nearly any blood type (except when the person has some rare antigen outside of the main ones).
