What blood types make a b negative?
At least one parent would have to be B or AB. The other could be pretty much anything. Both could be either positive or negative.
Yes. The different blood types are A, B, AB, and O. But, both A and B have two variations. A can be either AA or AO, while B can be either BB or BO. AB can only be AB and O …can only be OO. So, if the B parent has BO blood and the A parent has AO blood, each can give an O, resulting in OO blood, which would be blood type O. Here is a chart of the possible results if the parents are AO and BO: ......B O A AB AO O BO OO So, these parents can produce children with all four blood types: AB, A, B, and O. And, since one parent is Rh-negative and one is Rh-positive, the children could be either negative or positive.
If the mother has a negative blood and the father is b negative does that make the child ab negative?
No. If both parents have a negative blood type, the child will either have the mother's blood type,or father's blood type, or if one parent is A- and the other B- only t…hen can a child be born AB-. However, if two people with negative blood types try to have a baby, that may be very difficult. Sterility usually runs on the negative blood types, but conceiving a child is not impossible for them.
Not necessarily, it depends on the genetics of the parents.
Yes. 85% of the population is Rh+. Rh- is recessive . Type O+ and B- can make O+/- (or) B+/-
You can either be B negative, or O negative. You cannot be A, since it's a codominant type. You cannot be positive since negative is a recessive trait, and both parents must b…e negative/negative, then you must be as well. You could possibly be O negative if you inherit a recessive O from each parent.
I am uncertain whether or not it is true, but 30 years or so ago I read a book which indicated that people of Western European origin who were B-Neg had an ancestor who was Mo…ngol.
Yes! O NEG is a universal donor, so it is compatible with all blood types...
If you have B- blood: You can give to people with: B+, B-, AB+, and AB-. You can recieve blood from people with: B- and O-.
We are looking for the possible blood types of a baby. Parental information: Mother type O pos = can only be OO and Rh (++) or (+-) Father type B pos = can be… BB or BO and Rh (++) or (+-) Baby receives one gene from each parent: Baby is type BO (++) = Type B pos Baby is type BO (+-) = Type B pos Baby is type BO (--) = Type B neg Baby is type OO (++) = Type O pos Baby is type OO (+-) = Type O pos Baby is type OO (--) = Type O neg YES, the baby of O pos and B pos parents can be blood Type O neg.
A woman is homozygous for A-negative blood type. A man has AB-negative blood type. What is the probability that the couples child will be type B-negative?
No. If neither parent has an A or AB type, then there is no A gene to pass on to the child.
These combinations: A+ and B+/B- A- and B+ B+ and B+/B- B- and B+/B- B+ and O+/O- B- and O+/O- The A parents would have to be heterozygous for the A blood group.… The A+ parents would have to be heterozygous for the + rH factor. The B parents could be homo- or heterozygous for the B blood group. The B+ parents would have to be heterozygous for the + rH factor. The O+ parents would have to be heterozygous for the + rH factor. All the A, B, or O negative parents would be homozygous recessive for the negative rH factor.
The offspring of AB negative and B positive parents may be type A, B or AB, Rh positive or negative. Specific type depends on the genotype of the phenotypic B, Rh positive par…ent.
