Kinetics of Muller’s Ratchet from Adaptive Landscape Viewpoint

Webknown as (the Fleming–Viot version of) Muller’s ratchet, a population ge-netic model introduced by Hermann Muller (1964): A clonal population of ﬁxed size reproduces randomly. Each individual carries a number of muta-tions, all of which are assumed to be deleterious. Fitness decreases linearly with the number of mutations. Web1 nov. 2006 · The stopping redundancy of the code is an important parameter which arises from analyzing the performance of a linear code under iterative decoding on a binary erasure channel.
