Patricia  Glad to hear I'm not the only one!  Just to explain
exactly what were talking about here, the Rh gene is written
with a small r. So rh. rh is recessive in the Rh gene series. So
when someone has 2 x rh genes (small r) then this can be
detected so then they become Rh- negative. If you only have 1
gene (or even none) then your Rh+. So both your parents must
have at least one rh gene to give to you.  So, on occasions, a
female can be Rh-negative (2 x rh genes inherited from both her
parents) and her unborn baby is Rh+positive (the Rh+ obviously
comes from the father). If this scenario happens then some of
the unborn baby's erythrocytes can get d
