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.


My six children were born in 1963, 1964, 1966, 1968, 1969, and 1983. All of them received the Anti-D shots through my body as they were growing in my womb. In England, the UK. I know without a shadow of a doubt, it’s why all of them have Asperger Syndrome. I was the first ever to set up web sites for discussion on it in the UK. I was never told, despite asking often, what the jabs were for, and actually snapped at by male doctors/gynaecologists (no female doctors then) and l assumed all pregnant mothers had the same jabs too. Doctors were treated like god’s then, and mother’s like lumos of meat, without the right to speak. Try asking us, we were the targets of their actions. BTW, l hope everybody here is well, l’m now eighty, and this year, l had a joint stroke/heart attack, and am slowly dying if them both. So ask now, l may not be back. God bless you all. I’ve enjoyed your company, even those who don’t enjoy my own. God bless you all. JJ (Jeanie)
How can you be tested for weak D?
