There are three alleles for human blood groups. A, B and O.

A and B are codominant, so are expressed together when this genotype is formed. AB.

O is recessive and does not expresse unless it is homozygous recessive in expresion. OO. If, say, AO is the expression then only A would be expressed.

What if your blood group is AB positive and your wife's blood group is O positive She is now in her 30 weeks pregnancy What might be our baby's blood group?

Your baby could be either blood group A positive or B positive. Since the mother is O positive, she can only pass on an O allele. The father, being AB positive, can pass on either an A or B allele. So, the baby can inherit either blood type A or B from the father, making the baby either blood type A positive or B positive.


What are parents blood group with their first baby is of blood group o negative?

Can a man with blood group o positive be father to a baby with blood group o?

Yes, a man with blood group O positive can be the father of a baby with blood group O. Blood group O is inherited when a child receives an O allele from both parents, so the father must have at least one O allele to pass it on to the child.


What is the baby blood group if husband is A- and wife O plus?

The baby could have blood type A+ or A-. The Rh factor (positive or negative) is determined by the father's blood type, while the ABO blood group (A, B, O, AB) is a combination of both parents' blood types in this case.


Why the antibodies anti A and anti B in blood group O do not destroy cells of blood group A or B destroy?

They do sometimes. Sometimes an O mother's anti-A and anti-B antibodies come in contact with an A, B, or AB baby's blood and cause problems with the baby's blood by destroying its blood cells and the baby may need a blood transfusion.

Can father is A blood group and mother is B blood group and baby is male or female?

Yes, it is possible for a father with blood type A and a mother with blood type B to have a baby who is male or female with blood type AB if the baby inherits one A allele from the father and one B allele from the mother. In the ABO blood group system, the A and B alleles are codominant, meaning both can be expressed in the offspring.
