Yes, bloodtype is not directly hereditary.
If both parents have O blood type, the chances of their child also having O blood type is 100.
If both parents are type O blood they will only have type O children
Yes
No, two parents with type O blood cannot have a child with blood type A. Blood type O is recessive and a child can only have type A blood if they inherit an A allele from one parent and either an A or O allele from the other parent.
No. If both parents are type O, the child will also be type O.
No, two type O parents can only have type O children. See the table below from www.dna-bioscience.co.uk/did_you_know_abo.shtml If you look at the row for mother's blood type O where it intersects with the column for father's blood type O, you will see that the child's blood type must be O. For the child to be Rh+, only one of the parents has to be Rh+.
If BOTH the parents have Type O blood, then their child has a 100% chance of having Type O blood. If ONE of the parents has Type O blood, then it has a lower chance. For more information, look up "Punnett Squares"
Yes, according to the site at the link below, a child can have A- blood, given parents of O+ and A+.
The child's blood type is determined by his or her parents' blood types. If both parents have type A, the child can have either type A or O. If both parents have type B, the child can have either type B or O. If one parent has type A and the other parent has type B, the child can have type A, B, AB, or O, but he/she is most likely to have type AB. If both parents have type O, the child will have type O.
Yes, it is possible for parents with blood types O and AB to have a child with blood type O. The child would inherit an O allele from one parent and an O allele from the other parent, resulting in blood type O.
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.
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.
