Man has B Neg Blood, Woman has B Pos Blood, They have a Child she has A Pos blood, Is this possible?

Answer 1

No, first of all they should have have done an RH factor test because of you having conflicting RH factor. Are you positive of yours and you wife's blood type? If you are I hate to say that no it isn't possible. However, there have been stranger thing to happen and if you really want to know you can do a paternity test. There are ones that aren't admissible in court that are about $179.00. That will let you know without a doubt. The one word of advice is if you love both of them it takes more than sperm donation to be a dad so you are the babies father

Answer 2

I just read an article not too long ago that stated after more research into blood typing they now believe grandparents blood types to play a role in a childs type. I can't seem to find the article now it was in one of those science websites. Basically if any of the babies grandparents had an A in their blood type the baby could pop out with it. It's not necessarily likely but it could happen, my grandparents we B and AB and between their 6 kids there are 2 Os 2 B's an A and an AB.

Answer 3

No, when a guy and a girl has the same B neg. or B pos. the baby have to have or B neg. or B pos., but not A or other ones. Baby takes blood from parents or ether mother or father.

Answer 4

NO it's not. A person with B blood type either has BB or BO blood. You get one blood type gene from each parent. To have a child with an A, one parent would have to carry it and pass it on. One parent would either have to have A blood or AB blood. A DNA test should be done because something is fishy. The only clood type a child coming from parents with B blood, is B, or O if both parents carry and pass on an O blood type gene.

Answer 5

Parent 1 Blood Type: B
Parent 2 Blood Type: B

Possible Type of Child: B or O

- - - - - - - - -
Child Blood Type: A
Parent Blood Type: B

Possible Type of Other Parent: A or AB

*possible* blood type of a child, given the blood types of the two biological parents or the *possible* blood types of one biological parent, given the blood types of the child and the other biological parent. We emphasize "possible" because, in most cases, blood typing is not conclusive when attempting to determine, include or exclude an individual as the parent of an offspring.

This is based solely on theoretical principles. It would be a mistake to use this information to make any conclusions about your own family tree. Anyone wishing personal information about their own blood type inheritance is encouraged to contact their health care provider.

Answer 6

According to the table at the end of this website it is impossible for two adults with B type blood to have an child with A blood type.

Are you sure one of you isn't AB? Then it would be possible.

Answer 7

No, the baby should have either B+ or B-. 3 of my boys have A- , like me, and the last one is AB-. My husband is A-. You can either have the blood type of the mother or the father or a combination of both....but you can't have something that is entirely different.

Answer 8

No.
A child must have the blood type (and RH factor) of either the mother or the father. For this hypothetical child to have A Positive blood, his/her father must have A Positive blood.
That's the way it works.
Sorry.

Answer 9

I think someone been sneaking round, I actually took a course similar to this. If one is B- and one is B+ then the baby will be B- because the negative blood type is more dominate.

Answer 10

I am not a scientist, however I believe that if the father and mother are both Type B (regardless of positive/negative), the child must be Type B. Notice I said father and mother, not man/woman. Sorry.
