In brief: Functional v genetic

It is only minimally a genetic issue, based on blood group type which is readily found by decades old tests.
The primary HDN is related to Rh factor & seen if mom is Rh neg while dad is Rh pos & easily detected & avoided when properly managed. No other Rh pairing causes a problem. ABO blood group incompatibility produces minor HDN is some cases which is easy to manage.

In brief: Testing for HDN

there is cord blood testing for this.
It usually occurs with father with RH + and mother with RH negative testing.

In brief: Yes

Hemolytic disease of the newborn, causing yellow skin and eyes (jaundice) with anemia, is most commonly due to a "set-up"--a blood type difference between mother and child.
Blood types are caused by genes at the ABO and other loci (rhesus being most damaging), with o type or rh negative moms making antibodies to red blood cells of a or b or rh+ fetuses (if mom is o and fetus ab, baby switched), .
