WebThe above equations depend only on the relative fitnesses of the alleles. Therefore, we can measure fitness relative to the fitness of one of the alleles (a). W a = 1 . W A = 1 + s . s is known as a selection coefficient, which measures the amount by which fitness of a type differs from the fitness of a reference type (here a). WebCan a replicase be found in the vast sequence space by random drift? We partially answer this question through a proof-of-concept study of the times of occurrence (hitting times) of some critical events in the origins of life for low-dimensional RNA sequences using a mathematical model and stochastic simulation studies from Python software. We …
