WebHybrid dysgenesis is a direct consequence of mobilization of TEs in crosses between females that lack these TEs and males that carry them. The observation that the reciprocal cross does not produce dysgenesis indicates the presence of a cytoplasmic factor in the female germ line that prevents this mobilization.
