WebJun 28, 2024 · Population genetic analyses often use summary statistics to describe patterns of genetic variation and provide insight into evolutionary processes. Among the … In population genetics, the Watterson estimator is a method for describing the genetic diversity in a population. It was developed by Margaret Wu and G. A. Watterson in the 1970s. It is estimated by counting the number of polymorphic sites. It is a measure of the "population mutation rate" (the product of the effective population size and the neutral mutation rate) from the observed nucleotide diversity of a population. , where is the effective population size and is the per-generation mutation …
