WebDie Embryonalentwicklung umfasst die ersten 8 Schwangerschaftswochen. Der genaue Beginn der Embryonalentwicklung ist definitionsabhängig, meist wird jedoch die Frühentwicklung in der 2. Woche als Anfang gewählt. Das heißt, einige Schritte wie Befruchtung und Tubenwanderung finden zuvor statt. Cytoplasmic incompatibility (CI) is a phenomenon that results in sperm and eggs being unable to form viable offspring. The effect arises from changes in the gamete cells caused by intracellular parasites like Wolbachia, which infect a wide range of insect species. As the reproductive incompatibility is caused by bacteria that reside in the cytoplasm of the host cells, it is referred to as cytoplasmic incompatibility. In 1971, Janice Yen and A. Ralph Barr of UCLA demonstrated th…
