Контекст: • The possible association between hydatiform mole and preeclampsia supports the theory of genetic conflict in pregnancy. In the case of an hydatiform mole, there is an excessive placental proliferation without associated fetal tissues; there are 2 paternal genomes but no maternal genomes. The association of hydatiform mole and high levels of human chorionic gonadotropin (HCG) suggests that, in the case of preeclampsia, it is mostly via HCG that the placenta manipulates maternal physiology for fetal benefit.

В случае пузырного заноса имеет место избыточная плацентарная пролиферация при отсутствии тканей плода; пролиферирующие клетки содержат два отцовских генома и не содержат материнских геномов.
