The alleles for Immunoglobulins are carried on autosomal chromosomes, not on sex chromosomes. Hence, both parents are equally responsible for a baby's blood type.
They both determine blood type.
Nope.

First let Me say "Fathers don't have babys, Mothers do" To answer what I think is the intent of the question A AB B and O blood type is completely separate from RH factor which is + or - so The Fathers O blood type has absolutely nothing to do with the Rh factor of the babys blood. A father with Rh + blood can Father a baby with type O (or any other type) blood.
A B+ parent can have a child with A+ blood. The other parent must be type A or type AB for this to occur.
For a transfusion - blood type O can donate to blood type B. However, blood type O cannot except B-type blood. For offspring, with one O parent and one B parent - the child could be blood type O or B depending on the genotype of the parent with B-type blood.
No.
Yes, you can have a sister with blood type O and you can be blood type B. This can happen if you have one parent with type AB or B blood, and other parent with type O or B blood.
no, see chart: http://www.canadiancrc.com/Paternity_determination_blood_type.aspx
