If both parents have b+ blood type, can their child have a different blood group? And if the parents have 2 children, can only one child differ?

If both parents have b+ blood type, can their child have a different blood group? And if the parents have 2 children, can only one child differ?

Yes to both: If both parents are B+, any of their children can be either B+ or O+. Blood type is determined by the presence of either an A or B antigen, regardless of amount., with inheritance from both parents. B+ parents can be either BB or OB, . If both parents are OB, the child can be B+ (inherit a B from either parent) or be O (inherit an O from either) ...Read more

My blood type is completely different from my parents. How is this possible? My parents blood type is o+ mine is b+?

Genetics: Ordinarily, two parents both with blood type o cannot have a child with blood type b. There are a few rare ABO alleles, there is the possibility of a lab error, and there is also the possibility that one or both are not your biological parents. Ask each parent separately if you truly want to know and perhaps have trouble -- but decide first whether it's worth it. ...Read more

My husband and I both have a positive blood one of our children also has a positive the other o, how can that be? I don't know what our parents blood type.

My husband and I both have a positive blood one of our children also has a positive the other o, how can that be? I don't know what our parents blood type.

A+: A+ blood type means that one of the 2 blood type chromosomes (one from father and one from mother) carries a and the other carries either a or o: a+ blood = aa or ao. For one of your children to be a and the other 0, each of you must have one chromosome as a and the other as o (from your parents). Since each of you is ao, each child gets either an a or an o chromosome from one of you, so each child could be either aa, ao, or oo. Aa and ao = a blood type; oo = o blood type. ...Read more

Is there a way to find out your baby's blood type without tests if you know both parents blood types?

Is there a way to find out your baby's blood type without tests if you know both parents blood types?

No: You can narrow down what the blood type of the child will be however you cannot be 100% sure what the blood type of the child is without testing since either the mother or the father can donate the gene for blood type. ...Read more

What happens if two parents who's blood types are both b produce a child that has blood type o, what can you say about the parent's genotypes?

Homework problem: Probably both parents have one copy of the B allele and one copy of the O allele. There are other exceptional situations -- each parent may carry Bombay, which when inherited from each parent masks B. And there are some weak alleles. Enjoy your studies. ...Read more

What happens if two parent with o positive blood types have a child with b negative blood type?

Not possible: It is possible for the child to be rH negative if both parents are hybrid rH positive (one positive and one negative rH gene), but if they are both type O can only have type O children. Either one of them is not the biologic parent, or someone's blood typing is a mistake. Someone had to give that B gene. ...Read more

Could you tell me if my mom is o positive what are her parents possible blood types?

Blood typing: The 4 major blood groups are a, b, ab and o. If your mother is group o, than neither of her parents could be type ab. The others would be possible. Likewise, being rh positive means that at least one of your mother's parents were rh positive, but not necessarily both. ...Read more

Is there a such thing as C blood type? Is it possible for parents with B and O blood child to be C blood type?

Is there a such thing as C blood type? Is it possible for parents with B and O blood child to be C blood type?

Hemoglobin C: The main blood TYPES are A, B, AB and O. Perhaps you are referring to an abnormal hemoglobin type (Hemoglobin C) which can be detected on newborn screening results. Hemoglobin C is a structural variant of normal Hemoglobin A which may be of no clinical significance, or cause anemia and enlarged spleen. ...Read more

How often do blood type a- and o+ parents have a+ offspring?

Absolutely: An 'a neg' person can be ao or aa for the 'a' and must be negative/negative for the rh. So they can give an a or an o gene, but must give a negative rh gene. The 'o' blood type is only oo genetically, but positive/positive or positive/negative for the rh gene. So if the a gives an a and a negative, and the o gives an o and a positive, the child will be a positive, because these are both dominant. ...Read more

Can a child have a negative blood type if both of her parents are o positve?

Can a child have a negative blood type if both of her parents are o positve?

Yes: Each parent has two rh genes. It only takes one positive gene to make a person rh positive, so each parent can have a positive and a negative rh gene. Both genes have to be rh negative for someone to be rh negative. Since each parent only contributes one gene to child, the child can get a negative gene from each parent and therefore be rh negative. ...Read more

If one parent belongs to b blood type and another parent belongs to o blood type, is it possible for them to have a child with a blood type?

If one parent belongs to b blood type and another parent belongs to o blood type, is it possible for them to have a child with a blood type?

ABO blood typing is: Not sufficient to prove or disprove paternity or maternity because of possible testing difficulties. If concerned, consult your doctor. Chromosomal microarrays can be done on buccal swabs from parents ; infant by the lineagen company in salt lake city, ut, (801) 931-6224. If one parent has b blood type ; the other 0, one would expect their infant to have either b or o blood type. ...Read more

Can parents with b and o blood type can have a child with a or ab blood type? It is possible if any of the grand parents of the child have a or ab?

Blood type heredity: If the parents are definitely b and o then it would not be possible for their child to be either ab or a since neither parent carries the a antigen. The blood types of the grandparents do not have an effect on the grandchild. It is only the parents who influence the blood type of the offspring. ...Read more

Both parent has A blood type, can they have child with o blood type?

Both parent has A blood type, can they have child with o blood type?

Yes indeed: Blood cells show A or B antigens - if neither are present the blood type is O. A parent will AO or AA genes will be Type A. Since the child gets one gene from each parent - if both parents are AO and both pass the O to the child -- then the child will be O. The options are AA, AO, OA and finally 1 out of 4 gets the OO - and is type O. pretty cool stuff huh? ...Read more

Is it possible to have both parents with o positive bloodtype, but their child have o negative blood type?

Is it possible to have both parents with o positive bloodtype, but their child have o negative blood type?

Yes: The rh factor is inherited through separate genetic means from the blood type. The rh factor is a dominant gene, meaning only one gene is needed to cause expression of the factor. So two rh + parents can have a rh+/rh- gene pattern and have a 1/4 chance with every conception of having an rh-/rh- baby, 1/4 chance of rh+/rh+ baby and 1/2 of carrier rh+/rh-. ...Read more

What are reasons why there are different blood types and what do they do?

What are reasons why there are different blood types and what do they do?

Do nothing: Blood groups do not do any thing, with rare exceptions. They are variations in the genetic make up of different individuals. It is just like having different eye or hair colors. The different colors do not do anything and the same is true for blood groups.

Many: A+, a-, b+, b-, ab+, ab-, o+, o-. If you are getting a blood transfusion, there are many other factors to take into consideration.
