What children can be born from a marriage of two Rh negative parents?

What children can be born from a marriage of two Rh negative parents? In case one of the parents is Rh positive and the other is Rh negative? From the marriage of two Rh-positive parents.

Let’s designate the gene that causes the positive Rh factor as R, then the gene that does not lead to the synthesis of the Rh antigen will be designated as r.
Rh-negative parents have rr genotypes. They produce germ cells of the same type – r. All offspring have the rr genotype, the Rh antigen is not synthesized in their body. They are all Rh negative.
Rh-positive heterozygous person – Rr. It produces two types of germ cells – R and r. The offspring born to a marriage with a Rh negative spouse (rr, gametes – r) will look like:
children with a positive Rh factor (Rr) – 50%;
children with a negative Rh factor (rr) – 50%.
Rh-positive homozygous person RR produces the same type of germ cells R. From his marriage with a Rh-negative person (rr, gametes – r), all children will have the Rr genotype and will be positive for the Rh factor.
Both Rh-positive parents can be represented by options:
RR + Rr and Rr + Rr.
Marriage of a Rh-positive homozygous person (RR, gametes – R) with a Rh-positive heterozygote (Rr, gametes – R and r) will produce only Rh-positive offspring with genotypes similar to the parental ones (RR – 50%, Rr – 50%) …
The marriage of two Rh-positive heterozygotes Rr (gametes – R and r) will produce offspring of the species:
Rh-positive children, homo- and heterozygotes (RR, Rr) – 75%;
Rh negative homozygous children (rr) – 25%.
