yes they can..... positive and negetive blood group depends upon Rh factor and it is nothing to do with incomplete dominance of blood group.
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.
yes
If one parent is O positive and the other is AB negative, the child could inherit the A allele from the O positive parent and the Rh factor from the AB negative parent, resulting in the child being A positive. Each parent passes on one allele for blood type and one allele for Rh factor, so different combinations are possible.
absolutely. as long as one of the parents is positive, the child can be positive. and if one parent is A the other B, the child can be A, B, AB or O depending on the parents' other alleles. so the child can definitely be A or B positive, but also A negative, B negative, AB negative, AB positive, O positive or O negative.
Could be any type, we all get our blood groups from our parents or even our grandparents so, if your child is not B positve, your child will have the same blood group as one of its four grandparents.
rarely can be
If the mother has type negative blood, and the father and child have type positive blood, the mother's blood may begin to attack the child's.
it can be rare only
yes, absolutely
The child will probably be positive, but they can be negative. Each parent has two genes for pos/neg blood type. The parent will have positive blood type if at least one of their genes is positive, but they could both also have negative genes to pass on to the child.
no
No. A parent with AB blood cannot have a child with O blood type.

Yes! Parents have two genes for pos/neg blood type, and only one of them needs to be positive for the parent to have positive blood type. Most positive-blooded people have one positive gene and one negative gene. If both positive parents pass on their negative gene, they can have a child with a negative blood type.
