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%).
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 '+'
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.
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.
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.
Can parents b positive and O positive have a b negative child?
Yes, that's True. for Rh- to come, both parents should be Heterozygous.
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.
Can an A negative parent and a B positive parent have a B negative child?
Yes, it's possible but there are very slim chances. It depends heavily on the genotypes of both parents
What blood type can donate to AB negitive?
B Neg donors can donate to B Pos or B Neg patients.
Can parents that are both a negative have an ab positive child?
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
