What else can I help you with?
Can parents be B pos and have a kid A B p?
No. If both parents are B+ then their children will be B+ (75%) or O+ (25%).
If you have blood type O neg and your wife has O pos how is it possible for your baby to have B pos?
*Note from asker: Both my parents and at least one brother have B pos blood... Possibility of a throwback gene?
Is b-pos be the father to a-pos?
Yes it is possible if the mother is A positive or A negative.
How can a baby have b negative blood when both parents are b positive?
If both parents have Type B blood the only blood type the child can have is either B or O not looking at whether one of the parents is negative or not.
Can a b positive and a positive have a b negative child?
No. If both parents are positive, the child will be positive. If both parents are negative, the child will be negative. Parents who are negative and positive can have children who are either positive or negative. '+' + '+' = '+' '-' + '-' = '-' '+' + '-' = '-' or '+'
O pos and b pos parents have a a neg child?
No. Two Rh positive parents can have an Rh negative child. A parent with blood type O lacks the A antigen; a parent with blood type B also lacks the A antigen; therefore they cannot have a child together with blood type A.
Can parents b positive and O positive have a b negative child?
Yes, it is possible for parents with blood types B positive and O positive to have a child with blood type B negative. This can occur if the parents are both carriers of the negative Rh factor and pass it on to the child.
Can blood type O pos and B neg make B pos?
No, blood types O positive (O+) and B negative (B-) cannot produce a B positive (B+) offspring. Blood type O carries only the O antigen, while blood type B carries the B antigen. To have a B+ blood type, one would need to inherit the B antigen from both parents.
O negative blood produce child with o positive?
It really depends on what the other parents blood type is. One's Rh factor comes from both parents, one factor (for lack of a better word) from each parent. Someone who has a positive blood type has inherited either two positive factors from their parents (++), or one positive, one negative (+-) . Someone with a negative blood type has inherited two negative factors (--). SO...If one parent has a negative blood type (--), they could produce a child with a positive blood type if the other parent had a positive blood type, either (++) or (+-). If both parents are type negative (--), then technically it shouldn't happen that they would have a child with a positive blood type.Pictures below to demonstrate:http://www.childrenshospital.org/azSite639Imagesei_0375.gifhttp://www.childrensnyp.orgmschonyimagesui_0377.gif http://www.childrensnyp.orgmschonyimagesui_0378.gif Basically they are saying its not your kid and you need to get DNA to prove it.Additional Information: The O blood type is caused by a dominant gene. Two genes for blood type are inherited by a child, one from each parent. Here are the combinations of the genes that can be inherited and the blood types that will result: O and (A or B or O) -> O A and A -> A A and B -> AB B and A -> AB B and B -> B The "positive" or "negative" part is a separate issue.pos and pos -> pos pos and neg -> pos neg and pos -> pos neg and neg -> neg Keep in mind that a person may have type O blood, but have a recessive gene for type A or for type B that is being "hidden" by the O. The same goes for the positive/negative gene -- if you have a gene for positive, it will "hide" a gene that you may have for negative.I have type A+ blood and my husband has O+ blood. Our son is A+, so obviously my husband's genes are for O and A. (Since I have type A blood, my genes are both for A.) Our daughter is A-. So both children got 2 genes for type A. Both of us must have the "one gene for positive/one gene for negative" situation. Our son got at least one gene for positive. Our daughter got both genes for negative.
What blood types would produce a b negative child?
There is no single answer to this question. First, how does the child get type AB? The child needs to get an A gene from one parent and a B gene from the other, simple as that. This means neither parent can be type O because they would not be able to pass on the A or B gene (that is what O means, the absense of the A or B gene). If one parent is type A, the other must be B or AB. If one parent is B, the other must be A or AB. Also, both parents can be AB. In all cases, one passes on the A gene and the other passes on the B gene, that's it.Second, for the Rh factor (the positive and negative), the negative trait is recessive. This means the child must receive a negative gene from BOTH parents to display the negative phenotype. So the parents can be ANY Rh type. Why? Because it is a PAIR of genes, the GENOTYPE, that determines the trait. In the parents, they can be genotype +/- or -/+, meaning they have both the positive and negative gene and they can pass on the negative gene, but they will be POSITIVE Rh because that is the dominant trait. Of course, either parent could also be negative, -/- genotype, and they would certainly pass on the negative gene. So, you see, you cannot definitively type the parents in this case.
Can o positive and b positive create b negative?
No, O positive and B positive parents cannot have a B negative child. A child with B negative blood type must inherit a B allele from both parents, which is not possible in this scenario as the O positive parent does not carry the B allele.
Can parents with B positive blood type have a child with B negative blood type?
We are looking for the possible blood types of a baby.Parental information:Mother type B pos -- can be BB or BO with Rh (++) or (+-)Father type B pos -- can be BB or BO with Rh (++) or (+-)Baby receives one gene from each parent: Baby is type BB (++)/(+-) = Type B posBaby is type BB (--) = Type B negBaby is type BO (++)/(+-) = Type B posBaby is type BO (--) = Type B negBaby is type OO (++)/(+-) = Type O posBaby is type OO (--) = Type O negYES. These parents can have a child that is Type B negative.
