Typically the queen honeybee is mother to all the bees
in a hive; after mating with several maledrones from
other colonies,she lays fertilized eggs that develop into
Lineall-female
worker bees and lays unfertilized eggs that
5 become all-male
drones.According to natural selection
theory,a worker would enhance herfitness--or ability to
propagateher genes-by hatching her own eggs in addition
toorin place ofthe queen's.But a typical worker's fitness
would be diminished if other workers' sons,who
have
10 less genetic material in common with
the worker,
supplanted the queen's sons (the worker's brothers).
Researchers,testing the hypothesis
that workers usually
somehow block each other's attempts to
reproduce,put
unfertilized eggs laid by workers and
by the queen into a
15 hive.Other
workers quickly devoured the workers'
eggs
while leaving the queen's eggs alone.
这篇文章我可以翻译成中文,但就是不理解含义.“a worker would enhance herfitness--or ability to propagateher genes-by hatching her own eggs ”里的her own eggs是怎么得到的?“each other's attempts to reproduce”是指什么?
