Maternal-Effect Dominant Embryonic Arrest(Medea) factors are selfish nuclear elements that combine maternal-lethal and zygotic-rescue activities to gain a postzygotic survival advantage.... These factors, which we termed Medea(M) elements, are widespread in natural populations of Tribolium flour beetles but are otherwise unknown in the invertebrate world. 1, record 3, English, - maternal%20effect%20dominant%20embryonic%20arrest%20factor

Un exemple d’un système d’entraînement des gènes potentiellement viable est une unité gènétique appelée Medea, découverte dans le Tribolium [castaneum] et qui renforce la biosynthèse. L’élément Medea synthétique fonctionne en codant à la fois pour une toxine exprimée maternellement, et un antidote exprimé par la voie zygotique. La toxine exprimée chez la femelle provoque la mort de tous ses descendants qui ne possèdent pas l’allèle Medea, et dans la descendance qui porte l’antidote de sauvetage Medea, les protégeant d’une mort imminente. De cette façon, la proportion des individus qui portent Medea se trouve augmentée à chaque génération, et un gène rattaché, conférant une résistance au paludisme, pourrait ainsi aboutir au résultat escompté. Medea est ainsi capable de se propager rapidement dans une population. Medea est un acronyme pour maternal-effect dominant embryonic arrest, blocage d’un effet maternel embryonnaire dominant, faisant aussi allusion à la mère de la mythologe grecque qui avait tué ses enfants. 1, record 3, French, - %C3%A9l%C3%A9ment%20Medea

Un gen podría también adquirir ventaja eliminando durante la embriogénesis la descendencia de hembras heterocigóticas que carezcan del elemento egoísta a través de un efecto materno. Un caso bien conocido es el del “factor Medea” en el escarabajo Tribolium castaneum. 2, record 3, Spanish, - elemento%20Medea

[...] una clase de genes egoístas conocida como “elementos Medea”, [...] inducen la muerte de todos sus vástagos que no heredan el gen de las madres. No está muy claro cómo hacen esto, pero el gen probablemente codifica para ambos, una toxina y un antídoto, y si la toxina está de alguna manera presente en los huevos de la madre, los embriones sin el antídoto no sobreviven. 1, record 3, Spanish, - elemento%20Medea
