Abstract
This note is to correct an error in my paper, concerning the Shannon differentiation metric (D(Shannon)) (Reference [43] in the paper). The paper states that D(Shannon) is undefined mathematically whenever one or both populations are monomorphic, that is, fixed for a single allele. Accordingly, the D(Shannon) curve in Figure 1a, showing population differentiation in relation to allele counts for the case in which the pooled minor allele frequency (MAF) is maximal, did not extend across the full range of allele counts; the rightmost data point reflecting complete population differentiation was missing. Moreover, D(Shannon) was completely missing in Figure 1b visualizing the continuum of allele frequency differentiation when the MAF is minimal (one population monomorphic across the entire allele count range).
