Typically the queen honeybee is mother to all the bees in a hive; after mating with several male drones from other colonies, she lays fertilized eggs that develop into all-female worker eggs, and lays unfertilized eggs that become all-male drones. When a queen dies, workers often lay unfertilized eggs that hatch into drones. Yet workers rarely reproduce while a queen reigns.
According to natural selection theory, a worker would enhance her fitness -- or ability to propagate her genes - by hatching her own eggs in addition to or in place of the queen's. But a typical worker's fitness would be diminished if other workers' sons, who have less genetic material in common with the worker, suplanted the queen's sons(the worker's brothers).
以上便是原文(第一,二段). 虽然没什么单词, 但对第二段第二句的理解很有困难. 谢高人指点作者: maryland 时间: 2002-11-23 20:16
Typically the queen honeybee is mother to all the bees in a hive; after mating
经典上看，蜂后是一个蜂巢中所有蜜蜂的母亲，
with several male drones from other colonies, she lays fertilized eggs that
她与其他系源的几个公蜂交配后，产下受精卵，这些受精卵都会变成全雌性工蜂卵。另外，
develop into all-female worker eggs, and lays unfertilized eggs that become all-
她还产出非受精卵，这些非受精卵变成雄性蜂。当蜂后死后，工蜂经常产下能孵化成drone的非受精卵。
ale drones. When a queen dies, workers often lay unfertilized eggs that hatch into drones. Yet workers rarely reproduce while a queen reigns.
不过，在蜂后掌权的时候（存活的时候），工蜂是很少生产的。
According to natural selection theory, a worker would enhance her fitness -- or
按自然选择学说的说法，一个工蜂可以通过孵化她自己的卵来加强自己的适应性或增强自己
ability to propagate her genes - by hatching her own eggs in addition to or in
繁衍自己基因的能力，甚至取代蜂后的地位。
place of the queen's. But a typical worker's fitness would be diminished if
但这样的情况发生，工蜂的适应性将会降低，因为与蜂后的子女比，其他工蜂的子女与工蜂在遗传物质上有较少的共同性。
other workers' sons, who have less genetic material in common with the worker, suplanted the queen's sons(the worker's brothers).
