胎儿从父亲和母亲的基因中各接受一半的基因成分,胎儿红细胞可能携带来自父体的抗原,表现出来的胎儿的血型不同于母体。当胎儿红细胞进入母体的血液循环后,诱导母体的免疫系统产生抗体,抗体通过胎盘进入到胎儿血液循环后,结合胎儿的红细胞,使胎儿红细胞被破坏,导致胎儿和新 The fetus receives half of the genetic components from both the father and mother’s genes. The fetal red blood cells may carry the antigen from their father’s body, showing a different blood type than the mother. When fetal red blood cells into the maternal blood circulation, the immune system to induce maternal antibodies, antibodies through the placenta into the blood circulation of the fetus, the fetus with red blood cells, so that fetal red blood cells are destroyed, resulting in fetal and new
