You read a lot of stuff on an rh negative mother and rh positive father but what if it is the opposite with an rh positive mother and rh negative father?

People carry two copies of almost every gene, but they only pass one of them down to their children. Rh positive is dominant, meaning that if you have even one Rh positive gene, you will be positive.
Both parents can have one Rh positive and one Rh negative gene. If they each pass the Rh negative gene on to their child, the child will be Rh negative.

If mother is Rh+ with homo alleles (Rh+Rh+) all children are Rh+.
If mother is Rh+ with hetero alleles (Rh+Rh-) 50% of children are Rh+ and 50% are Rh-.
