Yes they can.
Yes, parents with blood group O positive can have a child with blood group O negative. This is possible if one parent is heterozygous for the Rh factor (one parent has both positive and negative Rh alleles), allowing for the possibility of the child inheriting the negative Rh factor.
No. A parent with AB blood cannot have a child with O blood type.
The possibilities include B positive, B negative, O positive, O negative.
Yes
Yes, the child of these parents could have either blood type O+, O-, A+, or A-.
Yes, the child of these parents could have either blood type O+, O-, A+, or A-.
Yes they can, First of all, the chance that they have an 0 child is 50%. It can be A of 0. The chance however that the child is Rhesus negative is 25%. So 0,5*0,25= 0,125 = 12,5 % chance the kid is 0-. RV
The father would be fat.
It is possible for a child to have a blood type that is different from either parent if both parents are carriers of a different blood type allele. In this case, the child could inherit the O negative blood type if both parents are carriers of the O negative allele.
No, an O negative child cannot have both parents with O positive blood types. While both parents can pass on an O allele, they would each contribute a Rh positive factor, resulting in a child with a positive Rh factor. For a child to be O negative, they must inherit the Rh negative factor from both parents.
Yes, the baby could be positive. If the baby is positive the mother needs to get on immuno-suppressant drugs or she will have an immune reaction and her body will try to kill the "foreign object" aka the fetus. Best of luck.
Yes, we all get our blood groups from either our parents and even grandparents.
