Can a mother with blood type O and a father with blood type B have a son with blood type AB?
HiLets answer this question step by step.Mother's blood group is O.O is recessive blood group meaning that it can not contribute to change in blood group in foetus by itself.However, if any other blood group gene resides beside O, say A or B, there is only ~20-25% chances that the foetus has O blood group.Now father's blood group is B. Since for the foetus to have blood group AB, it should have both A as well as B blood group gene.Mother is not providing any gene except recessive O.Father is providing B. ( Pure B genes or B and O genes) So no source of blood group A gene. Hence, there is no possibility of AB blood group in foetus.The only possibilities are blood group B (75-80%) & O (20-25%)If you like my answer, please follow me on quora. ~Arsh~
Can a mother with blood type O- and a father with blood type A+ have a child with B+?
Short answer: NoTake this question in 2 parts: First the ABO blood group:The ABO blood group is determined by the ABO gene, which is found on chromosome 9. The four ABO blood groups, A, B, AB and O, arise from inheriting one or more of the alternative forms of this gene (or alleles) namely A, B or O.So if parents are O & O child has to be OIf O & A……………………… O or AIf O & B………………………O or Bif O & AB…………………….A or BIf A & A……………………….A or Oif A & B………………………..O or A or B or ABIf B & B……………………….O or Bif B & AB…………………….A or B or ABif AB & AB…………………..A or B or ABRh is simpler+ & + can be…… + or -+ & - can be + or -- & - can only be -Hope thats clear!
If a father has an O blood type and a mother has an AB blood type, what will be the child’s blood type?
It would be either A or B blood group.As the father has O blood group( recessive and is expressed only if present in homozygous condition) so possible alleles are O and O.The mother has AB blood group, which means the possible alleles would be A and B.Thus, the child may either have AO gene pair (2 alleles make one gene pair) or BO gene pair. This implies that either the child would have A or B blood group as I mentioned earlier too that O is recessive and is expressed only in homozygous condition. And here the resultant being heterozygous i.e., AO and BO, O would not be expressed.Thank you
What is the blood type of the father if the child and mother both have blood type B-?
All the children will always have the Rh negative blood type because neither parent has that trait to pass on. Children will either have B (-) blood or O (-) blood. If both parents have only one B blood trait there is a chance that neither will pass it on to a child. There is a three-in-four chance that the children will be B - and a one-in-four chance that they will be O (-). If at least one parent has two B traits then all the children will be B (-) but those children will have the possibility of passing on O or B blood to their children.If a parent with AO (+) blood has children with a BO (-) person, their children could either have type A (-) or (+), Type B (-) or (+), Type O (-) or (+) or Type AB (+) or (-).Isn’t genetics fun!?!Update: I did misread the question! (Thanks Barry Gehm!) We have insufficient data to determine the father’s blood type. All we can determine is that he is not AA (++) meaning he has at least one non-A trait (B or O) and one non-Rh positive trait but he could totally be A (+ or -), B (+ or -), AB (+ or -) or O (+ or -). This is why DNA paternity tests have become so popular.My son and I are both AB (-) but that would never expressly tell you that my husband was A (+) only that it is possible that he is. He passed on his A trait, I passed on the B trait and neither of us passed on the Rh trait even though that is dominant. Both of my parents are Rh + but neither of them passed on the Rh trait to me.My son’s father could not have Type O (+ or -). That would exclude one blood group but not others.
What type of blood types could be found in an offspring, if the mother had type O and a grandfather had AB?
In order to identify the possible blood type of a baby or offspring, the mother and father's type should be identified first. A grandfather's blood type has nothing to do with identifying an offspring's type. Therefore, the information you have given is lacking because you only provided the mother's blood type. I would want to answer your query by doing a diagram of blood types of parents and offsprings but it would be very technical and not helpful. If the grandfather is type AB, the father could either be Type A, B, or AB... which makes it hard to predict. If you can message me with the correct information, i can send u back the answer.
