摘要

We analyze here the 演化ary consequences of selection with delay in a 族群 遺傳s context. In the classical works on 演化ary dynamics, an individual produces off-springs in direct proportion to its fitness, a process in which 突變s may occur. In the present scenario of delayed selection, individuals that acquire deleterious 突變s can still reproduce unharmed for several generations. During this time delay, the damage passed on to off-springs can potentially be repaired by subsequent compensatory 突變s. In the absence of such a repair, the individual becomes sterile. Here we study the 族群-遺傳 effects of such a time delay by means of both numerical simulations and theoretical modeling. The results show that delayed selection lowers the extinction threshold, endangering the survival of the 族群. Surprisingly, h
