Can blood be either B positive or negative?
Yes, butonly if both parents have the negative gene, but have a positive blood type because they have both the positive and negative gene. A positive blood type is dominant and negative is recessive. So if they have both and both pass down the negative gene the child has a negative blood type. And the child will either have an O or B blood type. Making a B negative blood type. I hope that helps :)
If father's blood group is O plus and daughter's blood group is B plus then what is the blood group of mother's and brother's blood group?
If the mother has B positive blood and the father has O negative what would the child's blood type be?
Blood groups are A, B, and O. Each type of blood is either positive or negative. When a couple is planning on marriage, their blood type is not as important as the positive or negative aspect. A woman with negative blood types may encounter problems having children if her husband has a positive blood type. All blood types are compatible as long as they are both positive or negative.
Yes, she can. As far as blood type goes, if one parent is O and the other parent is B, the child can be either O or B. For Rh factor (i.e. negative or positive), if at least one parent is positive, then the child can be either negative or positive. If both parents are negative, then the child will be negative. So, it is perfectly plausible that it is his child.
