In this paper, we show that for evolutionary dynamics between two types that can be described by a Moran process, the conditional fixation time of either type is the same irrespective of the selective scenario. With frequency dependent selection between two strategies A and B of an evolutionary game, regardless of whether A dominates B, A and B are best replies to themselves, or A and B are best replies to each other, the conditional fixation times of a single A and a single B mutant are identical. This does not hold for Wright-Fisher models, nor when the mutants start from multiple copies.
在本文中，我们表明，对于可由莫兰过程描述的两种类型之间的进化动力学，无论选择情形如何，任何一种类型的条件固定时间都是相同的。在一个进化博弈的两种策略A和B之间进行频率依赖选择时，无论A是否优于B、A和B是否是自身的最佳应对策略，或者A和B是否是彼此的最佳应对策略，单个A突变体和单个B突变体的条件固定时间都是相同的。这在赖特 - 费希尔模型中不成立，当突变体从多个拷贝开始时也不成立。
