All person are of A, B, AB, or O blood types, the positive and negative or is a protein antigen on the surface of the blood cell that cause a response from the immune system.
Rh factor is a type of patine on the red-blood cell surface, most people who have Rh factor are Rh positive those that do not have Rh factor are Rh negative.
When the mother is Rh neg. and the father is Rh pos. then the fetus can inherit the fathers Rh pos.
Usually in first pregnancies this is not a problem, but during the first pregnancy the mother will build antibodies to the Rh positive factor, and cross the placenta and attack fatal blood.
It like a allergic reaction if the Rh pos. factor of the mixes with the mothers Rh neg.
To answer your question!
if both parents have Rh+ blood with the +- genes, they could have children who are ++, +-, or --. so yes parents with positive Rh factor can have a child with Rh neg. blood!

It is only an issue if the Mother has the RH - factor if the first child is RH+ there is a problem as the Mother does produce antibodies against it. If the second child is RH+ it must receive a dose of ________ I cant think of drug name. If second child is RH- then there is no problem. and it continues that way for each subsequent child.

Both my parents were RH positive as well as all my brothers and sisters. I inherited a recessive gene that caused me to be negative.
I married a man who was RH positive our first son was RH positive. I had titer test done before giving birth to my second child ( due to not getting the antigen after the first childs birth) and being sensitized. The test showed I did not have enough antigens to harm the second child. After that I received the RHLG or also called RH Immunoglobulin to prevent any further pregnancy problems.

Absolutely! Rh + is dominant to Rh -, therefore both parents can have a recessive allele. Each parent can then pass that Rh- allele down to their child, who then would only have Rh- alleles and have a phenotype of Rh-.
So, yes, Rh+ parents can have an Rh- child.

YES.
In the Rhesus system, positive dominates negative, so if your genetic type is ++ or +-, your blood type will be Rh positive. You will be Rh negative only if your genetic type is --. If both parents have Rh positive blood and +- genes, they could have children who are ++, +-, or --. In other words, their children could be either Rh positive or Rh negative. Children who are Rh negative can have parents who are either Rh positive or Rh negative.

yes....I am have O positive Rh positive blood....my daughters father was the same
daughter came out with O negative Rh negative blood....she simply collected all the recessive genes....

Yes; The parents would have to both be +- (carriers, in other words), so that about 25% of their kids will be --, or rh negative.

No. One or both of you have to be RH negative in order for you to have an RH negative baby.

No, I believe at least one parent has to be Rh-
