A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).
for me i cannt rxplain that due i answer it by the formula of each genetic but i can explainwhy the bt o cannot transform it and my answer is 0 because in the patents doesnt contain bt o so the sibling cannot contain that ever if the one of the parents cointain and the other parents is not its authomatically o because o is the universal blood
lolCAN YOU DO ME A BRAINLEST ANSWER
The genotype must be AB
Because in most cases, an O parent and an AB parent will have only A or B kids. It is only very rarely that they might have an AB or an O child (see the links at the end for these exceptions). Isn't genetics fun! What I'll do for the rest of this answer is go through why an O parent and an AB parent will have only A or B kids.
Dad's blood type:
Its TYPE A ? Pls answer me
TYPE BLOOD AB POSITIVE
Using the Punnet Square, we can get the following combinations:
25% Blood Type A
25% Blood Type B
50% Blood Type AB
