Yes this could happen if the geno-type of both parents is heterozygous, what i mean by that is to have this symbol for both parents :
IAi X IAi
so to have a child with type O, the possibility for that is 25%
No
Yes. If both parents are heterozygous (rh+ rh-) for rh factor, they could each pass on an rh- allele to the child and it will be rh negative. As for blood group, as long as the child inherits either two A alleles (AA) or one A and one O allele, it will have the A blood group.
Yes, they would just both have to have one B allele and one o allele.
no. The ABO system and Rh blood group are already decided the moment sperm meets ovum. It is decided by the gene we have. For ABO classification, to put it simply people with A blood type has two A gene or one A gene plus one O gene. People with B type have two B gene or one B gene plus one O gene. People with AB type has one A gene and one B gene. O type has two O genes. A father passes one of his blood gene to his child and a mother passes one as well that the child now has two, and the combination is what decides the child's blood type. Bombay type is a very rare blood type different from A, B, or O. You can only have it if your family has a very rare gene, or in other words, if one of your family has it.
Yes parents who are both B blood group can have a child with O negative. This is because B blood group only requires one parent gene to be B to have B blood group - they may also have one O gene. People have two blood group genes, one from both parents. B gene is "dominant" as is A gene. O gene is "recessive". AB blood group means a person has one A gene and one B gene B blood group means a person has either one B gene and one O gene or two B genes A blood group means that a person has either one A gene and one O gene or two A genes O blood group means that a person has two O genes Rhesus positive or negative is similar - positive is dominant and therefore a person with one positive gene and one negative will be rhesus positive. A person who is rhesus negative has both negative genes, and received one negative gene from both parents, both who may be rhesus positive ( with one positive and one negative gene each). Importance of O negative blood - O negative blood group is called the "universal donor" because the blood is least likely to cause transfusion reactions so is safest to use in an emergency before blood groups can be identified and matched. If both parents are A+ can a child be B+?
No. One would have to be A or AB.
yes they can.Because there is two ways to express the A group persons that is either IaIa or IaIi ,if both parents are of the second type they can have a child that is O because the person of O type is expressed like this IiIi.
Only by adoption.... A person's blood type in the ABO system denotes the presence or absence of the A and B antigens. The antigens are molecules on the surface of the red blood cells; Group A people have the A antigen Group B people have the B antigen Group AB people have both A and B antigens Group O people do not have A or B Each person has two genes controlling their ABO blood type; one they inherit from their mother, and one from their father. The A and B genes, if present, will always be expressed, so it is possible to have an A gene and an O gene, but the blood type will be A. If a person is group O, then they have two O genes. If two people who are group O have a baby together, the baby will only inherit the O gene from each parent and will therefore be group O.
No
no, if both parents are A still there is a chance of O baby ,but for the child to have A blood type atleast one of the parents must have A or AB blood group Parents having the following blod groups may have an A baby AA and AA baby will have A blood group only AA and AO baby with A group only AO and AO baby may have A or O blood group AB and OO baby with A or B blood group AA and OO baby with A blood group only AAand AB baby with A or AB blood group AO and BO baby of A AB B or O blood group AO and AB baby of A AB or B blood group AB and AB baby having A B or AB blood group (each individual has one,two or no antigens .when no antigen it results in O blood group ,when one or two A antigens ,the person has A blood group so its not necessary that both parents of A blood group child have A blood type
Yes. If both parents are heterozygous (rh+ rh-) for rh factor, they could each pass on an rh- allele to the child and it will be rh negative. As for blood group, as long as the child inherits either two A alleles (AA) or one A and one O allele, it will have the A blood group.
No, there is no risk at all.
Yes, they would just both have to have one B allele and one o allele.
no. The ABO system and Rh blood group are already decided the moment sperm meets ovum. It is decided by the gene we have. For ABO classification, to put it simply people with A blood type has two A gene or one A gene plus one O gene. People with B type have two B gene or one B gene plus one O gene.

If two people with Type B blood have a child, the child will either be Type B or Type O.
