No. You cannot pass on a gene you don’t have.

Being Rh- means that you test negative for the presence of the
D antigen of the Rh Blood Group System.

There are more than 50 antigens in the Rh Blood Group System,
but the D antigen is the important one due to pregnancy issue
resulting from antibodies triggered in mothers lacking the antigen,
by a fetus whose blood stream carries it.

The so-called “Rh disease” or “blue baby syndrome” has been known of
since the late 1930s.

Rho(D) immune globulin has been on the market since the late 1960s.

Dating by Blood Type
has been invented by Mike Dammann in order to
provide Rh- women with the opportunity to select a potential partner
based on their Rh factor status.

Knowing that a couple with both parents being true Rh negatives
(not weak-D or partial-D), there is no chance for offspring to turn out
to carry the D antigen which might trigger antibodies in the Rh- mother
causing harm to be done to the Rh+ fetus.
