A genetic and metabolic basis for faster growth among triploids induced by blocking meiosis I but not meiosis II in the larviparous European flat oyster, Ostrea edulis L

This study establishes a genetic and metabolic basis to faster triploid growth in the oyster Ostrea edulis. Triploidy was induced using cytochalasin B, and image analysis of biopsied tissue employed to ensure similar ploidy of all animals within each class. Results indicate that lifetime growth in t...

Zusammenfassung:	This study establishes a genetic and metabolic basis to faster triploid growth in the oyster Ostrea edulis. Triploidy was induced using cytochalasin B, and image analysis of biopsied tissue employed to ensure similar ploidy of all animals within each class. Results indicate that lifetime growth in total dry tissue weight over 15 months was more than 60% faster ( p
