我们研究了在干雌性生命的初始阶段饥饿是否会影响后代的生殖特征。饥饿处理对休眠卵孵化的轮虫和无融合生殖卵孵化的轮虫有不同的影响。当干雌性经历饥饿孵化后，这诱导了较高的比例mixis在他们的后代。当同样的饥饿处理应用于从无融合生殖卵孵化出的轮虫时，对混合生殖的诱导没有影响。从休眠卵中孵化出来的干雌性可能具有易受不利环境条件影响的特定特征，并且这些特征可以通过母体细胞质遗传给后代。
We examined whether starvation during the initial period of life in stem females affected reproductive characteristics of the offspring. Starvation treatment had different effects on rotifers hatched from resting eggs and those hatched from amictic eggs. When stem females experienced starvation after hatching, this induced a higher percentage of mixis in their offspring. When the same starvation treatment was applied to rotifers hatched from amictic eggs, there was no effect on the induction of mixis. It is probable that stem females hatched from resting eggs have specific features that are vulnerable to unfavorable environmental conditions, and that these features can be inherited by their offspring through the maternal cytoplasm.
