You need to talk to a qualified medical practitioner (a Doctor) about this.
it is unlikly, but posible
no
the child has o negative blood
There is a 50% that offspring will be Rh negative.
Yes. My mother is O positive and my father is O negative and I am O negative
The blood type of any children would depend on the zygosity in the woman. (Both O and Rh negative are recessive, and will be homozygous in the man). If the woman is homozygous B, then the children will B. If the woman is heterozygous B, either O or B (with 50% chance of each). In the same way, if the woman is homozygous Rh positive, then the children will also be positive. If the woman is heterozygous, then children will be either positive or negative. In short, the possibilities for child blood types are either B or O, with Rh positive or negative.
Yes, it is possible for an A positive blood type man and a B positive blood type woman to have an O positive child. The child would inherit one A allele from the father and one B allele from the mother, resulting in the child having an O blood type.
Yes
I believe the answer is yes
The child will be able to have either a or o blood and either positive or negative. Mum will be oo genes and either +- or ++ rhesus. Dad could carry aa or ao genes and will have ++ or +- rhesus. So child could be ++ +- or -- could also be ao or oo.
Yes, a B positive woman and an A negative man can have a healthy baby. The ABO blood group system is separate from the Rh factor, so compatibility in ABO blood type does not play a role in potential issues during pregnancy. However, if the woman is Rh positive and the man is Rh negative, the baby may be at risk for Rh incompatibility, which can be managed with proper medical intervention.
The genotype of the man is A negative/O negative inheriting the A neg from his mother and O negative from his father. [Father's genotype is B positive/O negative. Mother's genotype is B positive/A negative.]
