rh- female populations are half-infertile and/or functionally infertile as a population towards rh+ male populations, due to the female producing antibodies that prevents them from giving birth to more than 1 rh+ baby. blood-shenanigans of old times and modern technology has allowed us to force rh- women to give birth to more than 1 rh+ baby. this is a literal genocide of a specific immune system type, which is the first objective step towards speciation.
