The parents could be a dominant A with an o and a dominant B with an o. The A and B are dominant, and the o's are recessive. The children can get 2 o's, one from each parent and they would then have o blood type.
No. It is not possible for a child to have A if the parents are O blood type. If both parents have type O blood, then their children will also have type O blood. However, two parents with type A or type B blood (both the same or one of each) can sometimes have a child with type O blood. That is because the gene for type O blood is recessive. But they must carry the O type. However, two parents with type AB blood can have a child with type A, type B, or type AB blood, but cannot have a child with type O blood.
If both parents are type O, they will always produce type O offspring.
They could, but they don't need to. Both of your parents must have at least one O allele, meaning neither can have type AB blood. They must be either BO, AO or OO to produce a child with type O blood.
If type O and O mix can they have a baby with B
No they cannot. They can only have a child with type A or type O blood.
a,ab
The gentotype is ii that will produce blood type O. The allele i is recessive, so both parents must have at least one i allele, and the child must be ii (double recessive) to be blood type O. The parents' blood types do not have to be type O- the genotypes Ai (blood type A, as A is dominant), and Bi (blood type B) can produce blood type O offspring, as long as the child inherits the i allele.
no
Blood types that produce anti-B antibodies include type A and type O. Individuals with type A blood have A antigens and produce anti-B antibodies, while those with type O blood lack A and B antigens and produce both anti-A and anti-B antibodies. Therefore, only blood types A and O can produce the antibodies against type B antigens.
It is not possible for two parents with blood type O negative to have a child with blood type AB. In the ABO blood group system, type O is recessive and AB is a combination of A and B, making it impossible for two parents with type O blood to produce a child with type AB blood.
Only if your mother was very friendly with the postman
An A blood group father can have an O type child. If he does, then he is heterozygous for type A.
Nope.
of course why not
yes
Yes, an individual with blood type B can produce an offspring with blood type A. The explanation for this is that a mother with the blood type A can have a child with a father who has a blood type of A or AB and produce a child with type A blood.
O positive or O negative.
