摘要
Understanding how 遺傳漂變, 突變 and selection interplay in determining the 演化ary fate of 族群s is one of the central themes of 演化ary Biology. Theory predicts that by increasing the number of coexisting beneficial alleles in a 族群 beyond some point does not necessarily translates into an acceleration in the rate of 演化. This diminishing-returns effect of beneficial 遺傳 variability in microbial asexual 族群s is known as clonal interference. Clonal interference has been shown to operate in experimental 族群s of animal RNA 病毒es replicating in cell cultures. Here we carried out experiments to test whether a similar diminishing-returns of 族群 size on the rate of 適應 exists for a plant RNA 病毒 infecting real multicellular hosts. We have performed 演化 experiments with tobacco etch pofy病毒 in two hosts, the natural a
