Yes.
Yes.
Yes, it is possible for both mother and father to be RH positive and a child to be RH negative.
mother could be either B or AB and she could also be Negative or Positive.
No. The mother must be either AO or AA, and the father OO. No combination of these can give rise to an AB child. However, a negative mother and a positive father can have a negative child, by rhesus factors, if the father has genotype +-.
Yes. I am O positive and my husband is A positive. We have two A positive children and one O positive child.
The child can have either Rh positive or Rh negative blood. More information is needed on the mother's genotype to know for sure. With the information currently given, the child has a 25% chance of being Rh negative.
The quotient of a positive integer by a negative is always negative. Say this to yourself a couple times: "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)"
A positive with highest probability
I honestly don't know :D but heres something to help you "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)"
positive plus positive equals positive negative plus negative equals negative
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
negative plus positive equals to zero
