Proteins in the blood are what decides your blood type. An O has none of these proteins, an A has either AA or AO, a B has BB or BO, and an AB has A and B. When a child is born it gets one of these blood proteins from its parents. If an AA and a BB parent mix the only option is AB. AO and BO could turn out as an AB, AO, BO or and O. If one parent has an AB the parent would pass on either the A or B protein. Since A or B is always dominant over O, no matter what the other parent had, the child would have to be and AA, AO, BB, BO, or AB.
A parent with AB blood could not produce a child with type O blood.
Yes! You could produce a child with either A or B blood.
No.
The parent with type O blood will produce gamets of IOIO and other parent with type ab blood will produce the gamets of IAIB so after mating the probability of progeny is IAIO:IBIO = 1:1 but no IOIO so in above case the probabitly of child with o blood group is zero or nill.
No. The A parent could be AA or AO and the rh factor could be ++ or +-. The O parent can only be OO and the rh factor could be ++ or +- They could produce an rh negative child if both parents are +- (heterozyous). Since neither parent has the B blood group it cannot be passed to their offspring. (Rarely, a parent could be a chimera and in this instance an abberant child could result from a mating between parents that appear totally normal...the operative phrase here is "Rarely!").
No. The child can only inherit what his parents have. If either parent had an A in his type, he could give it to the child, but the father is B and the mother has neither A nor B. (If either parent had an A, it would show up in his or her type.)
No. The child can only inherit what his parents have. If either parent had an A in his type, he could give it to the child, but the father is B and the mother has neither A nor B. (If either parent had an A, it would show up in his or her type.)
The child could be A+ or O+.
yes, the other parent could be: A+, A-, AB+, or AB-
No. They could have an A- child, but not A+.
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.
At least one parent would have to have an RH Positive blood type. Beyond that you can not tell. Because the O trait is a recessive trait, either parent could have A or B or O blood, since, for example, a parent with A blood could have one A gene and one O gene that together would express the A trait. That parent's child could inherit either the A gene or the O gene. The other parent could have B based upon one B gene and one O gene that together would express the B trait. That other parent's child could inherit either the B gene or the O gene. Only if the child of both parents inherited an O gene from each parent, would the child have O blood. As to the RH factor, it is a dominant trait, so that if the child has the trait expressed, it would have to have been in one of the two parents. Hope this helps.
A child with a parent with A positive and a parent with type O blood may be type A or type O. Without knowing the Rh factor of the second parent, it's not possible to say whether the child may have Rh negative blood.
